Simon Lizotte just gave a shout out to DGDU on the Nick and Matt show. He said he watched your videos to learn about MVP discs during his transition to Team MVP.
This is the best explanation of the manufacturing process, coupled with the plastics shrinkage and it's effect on the finishing shape, that can be found! Remarkably well explained and perfect visuals. I have heard that beat in disc fly more understable because the nose has gotten bent downward and this backs that right up. Great video man. Disc golf needs people and channels like you!
Cosmic neutron should be a plastic category as well due to the fact they are made with a slightly different blend of plastic. Cosmic neutron tends to be one of their most overstable blends of plastic. Love the vid, wish everyone was this dedicated.🐐
huge MVP/ Axiom fan, for all the wrong reasons.. The colours and naming culture. Turns out, nice discs to throw as well. Beginner player in my 50s. Great video.
I think to remove another variable, this could be done with Streamline discs. That way you get the MVP plastics but without the overmold. Either way, this is something I’ve been wondering about a lot lately. I currently have an Electron variant Envy and a Prism Envy in my bag at all times (among other MVP/Axiom discs as well).
I was thinking along similar lines for a follow up. Testing with an MVP disk so that the outer rim is all GYRO, seeing as the Axiom discs have different rim plastics. Seeing as in theory most of the aerodynamic properties are in the rim, having a consistent rim plastic would in theory more consistency across the plastic types. Even if it isn't more consistent, it should isolate the effect of the type of core plastic on stability.
I played a round with a guy visiting from out of town and gave him my backup bag, except he had an absolute cannon for an arm and flipped over every disc in that bag, except a neutron envy(2022) which he could mash on and it would not flip on him. He ended up throwing it off the tee almost every hole and was out driving me easily. It wasn't flying anything like your neutron envy. I think MVP's manufacturing consistency isn't what it was a few years ago, they are making 10x as many discs as before and with the increase in volume and having so many more molding machines they just can't keep the same level of consistency as they used to. I still enjoy and bag plenty of MVP, but its time for people to stop bashing on Innova for disc differences while praising MVP for their incredible consistency, that just isn't the case anymore. MVP is with the big dogs now, mass producing semi-consistent plastic like the rest of them.
Total agree, I was shocked, been throwing waves for years because they flex easily with my low old man arm speed. My last one would not flip at all ever.
First time seeing one of your videos. It was great! I particularly liked the release angle lines that you have the flight lines. It gives a ton more information that someone just saying, "released on hyzer".
Excellent video. I love it when content contains math/physics (actual science) to verify or debunk a theory and this test definitely had an unexpected outcome. Thank you.
When I started throwing 7 years ago, I leaned hard on innova and became well versed in their lingo. Since then, I've opened up my bag to other brands. As a fan boy of james and simon, I've gone deep into the mvp brand but I've had this lingering habit of comparing all brands of plastics to innova. So, if the plastic is translucent, it's Champion. If it's opaque and shiny, it's Star. etcetera. But after watching your video, and combining your results with my experience, iv opened my eyes to how that's just not the case. Thanks for conducting the science! Awesome vid
Interesting video, and appreciate the depth of the video! Would be interesting to see this test after the discs had some use. Perhaps adding the durability variable would sit the plastics in a predictable order, because in reality we are not throwing brand new discs each round. Obviously this is hard to test, because how do you wear each disc to the same level? But if we could add durability to the test by adding some wear, we would compare the plastics as most players will see them.
Conversation with Mrs Down Under goes something like this: "My fans want me to go out and buy the Volt in every available plastic". She responds with: "Yeah right, what fans". 😆
Loved your approach here. Would love to see a follow up where you compared consistency of same mold AND same plastic across multiple discs to see how much variation a single mold plastic combo has and then place those discs on the same spectrum you found in this video. Do all neutron Envys fly more understable than the Electron you tested? Etc.
if you look close on the picture at 14.51 you can see that the disc on the left has higher shoulder which gives it more stability than the disc on the right
I love a well researched and executed set of disc golf experiments like this. I'd be curious to see if you'd get the same performance results with a handful of other people repeating the experiment.
I really appreciate the thoughtfulness and effort you put into this video. I think that, while you did your best to account for and neutralize as many variables as possible, its nearly impossible to gather both reliable and valid (in the scientific meaning of these words) data with a human throwing. I think the factors most likely to confound data in this experiment are 1) your knowledge of which plastic you are throwing and your expectations of said plastic and 2) your natural release angle variance from shot to shot. Put those two factors together and who knows? This type of experiment usually comes back to the idea of "wouldn't it be great if we had a machine that could repeat throws with specific release angles, power, and RPMs?" It is reassuring to me that Eclipse tested near the top (OS) while Electron was near the bottom (US) as I bag Envys in both of those plastics. I live in Denver, CO and at 5,280' of elevation see them behaving according to this experiment, although I haven't thrown them too much at lower elevations...I wonder how "flippy" they might behave until I can find the appropriate release angle? Anyway, fascinating stuff. Thank you for this video!
I've been throwing more molds and plastics from MVP/Axiom, and I think you're spot on for stability. Especially with Eclipse 2.0 being the beef! I have a wave in it, and it's my night round forehand power disc, which is crazy since it's billed as a roller disc in neutron. I do have a prism pyro that's definitely more stable than my eclipse reactor, but you can't compare when two variables are changing.
I am not surprised at the outcome. I bag mostly Innova and I found the best way to deal with stability issues is to buy different molds in the same plastic. All my understable to overstable midranges and drivers are in Star plastic, and I use one of each mold. So for example My Teebird, TL, FD, and IT are perfectly 1 degree apart in terms of net stability, and I also bag a Champion Teebird to be 1 degree more stable, and on the other end a Star Leopard I used so much over time it's a tick less stable than the IT, which made it into my bag to fill the gap the Champion Leopard3 filled. So I haven't had to do a ton of hunting around for the perfect range of stability of discs. Heck I buy mostly standard runs, or factory second runs to save money. I don't beat and cycle in Teebirds for example. 🙂
I really appreciate the thoroughness of the system here, the theoretical vs the practical. As someone in the middle of their engineering nothing like more data to feel as the a problem is completely answered. I wonder if the results would be any more definitive with higher speed discs, slower discs seem much more effected by other forces even when thrown consistently.
Whoa.. That Neutron Envy is an anomaly. Flies more like a Proxy than an Envy. I have a few un-thrown neutron envy's that I'll need to test out. I've always just bagged the old soft neutron ones.
This is exactly what we needed! I tried to do this experiment myself a few weeks ago but I realized I'm not consistent enough because one throw eclipse would go dead straight and then next throw it'd fade hard. Surprised to see soft neutron more OS than regular neutron. I have uplinks in both and the soft neutron is noticably more undestable. Might have to dig my soft neutron and prism envy's out of my backup bin!
I was honestly surprised that people figured the plasma plastic would be near the least stable. I've got a plasma envy in my bag that started out as an absolute beefcake. The thing flew like a glidier overstable zone when I first got it, or what you might imagine a brand new, domey, 175g champion pig would fly like if they made those. I had an electron envy and had thrown new neutron and eclipse envies, and they were nothing like it. Neutral flyers, very mild low speed fade. Maybe my envy is an outlier, but the thing is still reliably overstable even 5 months of throwing it later. Not one single hint of turn out of the thing even now, even throwing it 300+ ft.
It was really crazy to watch the different flight of each one in the flight test part, and this had the best explanation for why different plastics in the same mold *should* fly differently that I've seen, even if that's not necessarily how it worked out when they were thrown. I think the video does hold some clues for why the final ranking ended up as it did. Besides the eclipse plastic, which you point out is more rigid because of the glow filler, it seems like the flight test stability results follow the total height on the chart at 16:31 more than they follow the putting line height, at least where the mold is the exact same. And, maybe the reason the eclipse plastic defies this is in its much higher rigidity in the air...it likely holds its form better than the other plastics, preventing any bend in form at the leading edge of the disc when it fights through the air. I could imagine (having never seen it tested) a slight natural "buckling" of the front of the disc as it flies and spins, dropping the putting line height slightly and reducing the stability.
A wonderful and succinct review of this topic! Impressive execution in this brief format. I bet an extensive review could be hours long with a lot more money and time invested. Which I’m not suggesting! This did the job, it’s just an insanely complicated topic
Because of course there is a difference between high speed stability and low speed fade, the difference with drivers and putters, sometimes the colors make a difference and sometimes they don’t, domey vs. flat-top discs, the dynamic effects of wear, temperature, etc. … the list is too long. Darn, it’s an expensive hobby 😅
Very cool video. I recently swapped out my Eclipse 2.0 Envy out for a pretty new Electron Firm Envy (I live in Oregon and it's wet this time of year). Kept throwing it into the weeds on the right because it's so much less stable. So now I've swapped to my lab 2nd Electron Entropy (very beat in), and it's money.
I think part of the issue when ranking stability of plastic is each run seems to be entirely different. I have an old proton envy that will finish as hard as any tactic I throw. (500+ thrower for reference)
100% agree. I think it's impossible to get reliable data between the plastics until the runs get more consistent. I have a soft neutron Envy from the recent run and it's soooo beef. More than any other plastic I've thrown (thrown all except prism). I love it though.
Thanks for you work. I agree with the Prism being more OS than Eclipse, but I love my Prism Plasma Envy for that. I was shocked that Neutron was so flippy. From what I have thrown, it seems like Plasma is more understable. As for Fission, it can be whatever you want as it will hold any line.
Amazing job on the experiment BTW. Biggest issue is that neutron is a lab second. Could be rejected as a startup or something causing the thing to be different. Buuuut I wonder if indeed the biggest driver of stability change is lot to lot rather than plastic to plastic. Probably just need to measure the population instead of just a sample. 🧑🔬
The neutron finding surprised me. Were you able to replicate that understable flight in a regular neutron envy and not just the lab second neutron envy?
My regular Neutron Envy is not that understable but it's also a much older disc from the same time frame as my Soft Neutron Envy which was pure beef when I first got it.
I feel as though the argument of different colors of the same disc in the same plastic should be at least considered, or perhaps would lead to an easier experiment. That or needing to increase the sample size of each different plastic, i.e. perhaps 10 of each plastic.
I bag an Envy and Proxy, but they're both electron firm. I bag two Insanity, fission and cosmic neutron Insanity. The cosmic neutron is significantly more over stable than the fission. I bag a neutron Crave and a fission, and the neutron is slightly more overstable than the fission, same with the Reactor in the same plastics. On a related note, I absolutely love the fission plastic. Love love it.
In my experience both plasma and eclipse beat in quite quick, although they start most overstable. I've thrown atom, mayhem, octane and matrix in multiple plastics and proton is the most consistent to flight numbers, neutron is slightly more stable but perhaps wears a bit faster. Never seen an overstable electron disc. To me it makes a lot of sense. Especially if prototyping is done with proton.
If I was to repeat this with another disc it would be the Volt. I've got it in Plasma, Proton, Cosmic Neutron and Fission. However, the Comic Neutron is one of the most stable discs I've ever thrown and nothing like the numbers.
@@DiscGolfDownUnder any experience with the electron? I ask because the flight number change to the electron is more drastic than the envy going from -.5 and 2 to a -2 and 1.5
I have a Cosmic Neutron, Proton, and Electron Volt all max or near max weight. Cosmic Neutron = total beefcake Proton = overstable Electron = straight stable but beats in fast and then is very accurate to the adjusted electron’s flight numbers.
Can this experiment be run again with the Hex or Crave or even a Proxy to see if the experimented stability differences you perceived on the envy hold true to another mold?
The more I throw MVP, the more I doubt the standard common beliefs in ranking of plastics stability. I believe the differences are not as large as single mold discs because the outer rim is the same plastic regardless of the inner plastic (except for prism and maybe electron?) I think the thickness of the rim compared to the plastic in the inner core also plays a factor in the shrinkage of the rim. When i use the plastics in Streamline single mold discs, I notice a much more dramatic difference in stability between plastic types. For example, the proton Jet is much more stable than the neutron Jet.
I've come to the same conclusion myself. You just have to try different plastics for every mold. My proton Crave is very flippy, while my proton Volt is a beefcake, f ex. I can slide my fission Wave's edge beneath my plasma Wave's edge when comparing side by side. They're not the same disc at all.
Would angle-of attack, or the angle of both the bottom leading edge and the top leading edge (vs flat) be a useful measurement? Your most overstable disc appeared to have a 'hump' on top that lead to a blunter (or more vertical) top face and the bottom wing edge (below the parting line) appeared to be blunter as well. Of course, the photo angle and color may be affecting my perception. Thoughts?
I looked at lots of different measurements but I couldn't spot a pattern in any of it. I think there's just too many variables in how disc flies including the plastic and also how much it is beaten in. If they were all the same plastic and level of wear I think it would be easier to compare geometrically.
I'd be interested to see how Fission plastic fits in this stability spectrum. Some anecdotes suggest that Fission is more stable than the numbers suggest.
11:00 Asking for the engagement boost for the video, and because I am really curious... in your test you discarded 20% of the throws for being "bad throws." Generally, during play, do you find that to be the going rate? One bad throw in five?
Depends on the day. Some days I can have a round where everything is almost perfect and other days you just wish I'd never gotten out of bed. I find that during these types of review videos that I do get tired the more I throw and the percentage of bad throws goes up at the end, to the point where I say that's enough, time to go home.
Great video mate! Please do more of these with other MVP discs =) Shoud the Prism realy be different becuse of the rim plastic? Other than the rim being Proton its no difference from a regular Proton, Neutron or Plasma?
@@DiscGolfDownUnder Thanks for the reply! I wish you a speedy recovery. I just found drjeremysteel and disc golf strong here on youtube and it was just perfect for me. Maybe they can help you too. Good luck!
I'm certain that the Glitch has enough flex that it's shape changes in flight due to aerodynamic pressure. My guess is it increases in stability the faster it is thrown but it's only a theory.
I just did the same thing with the crave and virus. Virus- proton understable will stay going right, neutron - more stable will fight back Impulse neutron way understable Crave- proton understable, neutron- stable, plasma overstable I throw the crave about 330 as a max and mainly around 275-300
The shape of the disc in flight should be considered, a pliable or gummy disc when thrown may have a different shape in flight than when it is static. I have found that gummy discs with OS molds will be more overstable and understable molds more understable. In my opinion this is due the centrifugal force causing the parting line to deform either up on OS and down on US molds (gummy molds in winter flying more or less stable would be a good test). The dome of the disc in flight will have similar effect due to the lift and centrifigual force on the disc. The other variable that can be considered is the grip of the disc and how it may create more spin based on the tacky plastic. Last variable I can think of is the pliability of the disc causing off axis torque.
There are so many variables and I'd love to explore them all. Hopefully MVP will learn heaps when they get their disc throwing robot up and running. Would love to be on that project.
What about Fission plastic? Yes I get it’s lighter but what if I bought a 175G fission HEX where would that line up in stability? Does anybody have an answer?
My experience with Fission is that it beats in faster than Neutron or Proton. Max weight usually starts out more overstable but quickly evolves to something more flippy.
This was a fun one. I think how domy the disc is changes the parting line height. The under stable envy looked domier, which would make the effective PLH lower.
You might have missed it but I also measured the disc height and calculated the parting line height as a percentage of the total height which takes into account the dominess. I think there was one Envy which was more domey than the others. I tried to see if either measurement method worked but they didn't.
I love envy’s and insanity’s. I can tell you these two molds are different. Prison Envy - OverStable Prison Insanity - Flippy Eclipse 2.0 Envy - Stable Eclipse 2.0 Insanity - OverStable++ Plasma Envy - OverStable Plasma Insanity - Stable Plasma Insanity - Stable
"Out of the box" stability vs. "After three rounds" stability. The more rounds you play with those discs, the more you'll see it line up with fan reviews.
This was the reason I switched from Innova to MVP. It was the old every Destroyer is different. I must have spent hundreds of dollars trying to find another Destroyer just like the one I lost.
It’s really all about “runs” like he described in this video. Manufactures switch up blends, pros ask for certain characteristics, different plastic types etc. If you find a holy disc, go back and buy five more of that run
I already knew prism is most overstable purely based on the density of the rim. The compact blend to make the plastic means only the biggest arms can turn for example, the prism tesla.
what about the flexibility of the plastic? more flexible may yield more off axis torque and more understable flight. another thought, look at not just the parting line but the curvature of the top of the disc. a flat top will have more upward torque and therefore overstable flight. domey top has more torque on the top front of the disc causing the understable flight. anecdotally, my neutron hex is surprisingly over stable. so maybe it's mold dependent and there are other variable too.
I agree about the flexibility, it tends to be an overlooked aspect in these plastic stability videos. But the effect of dome is known to vary with the mold, domey discs tend to glide straighter, so flat discs can be on either side of that.
Great video and thanks for the effort. Based on my experience, your experience and THIS experiment I would hypothesize that you could stand at the end of the production line for a given mold in a given plastic, go to the field and throw them, and be just as surprised with those results as we all were with the results you brought us in this video. End point: You gotta hunt/find the disc YOU need in a given mold taking into account the available plastics ... great for the disc manufacturers ($$$), not so great for us. :) Cheers! Love your channel!!!
Given that MVP because of the overmold produces discs with two different plastic types I would also hypothesize that this exacerbates the confusion ... Still, I throw MVP. I love MVP and will continue to do so. Luckily for ME, part of the fun of disc golf is buying/trying new molds, old molds in different plastics, going to the field and seeing how they fly. Then building my bag to better my game on the course. It's a journey and I SO love THIS journey. Also, I have never met a person on the disc golf course that I didn't get on with swimmingly, thus I theorize that the disc golf community is filled with some of the best people on the planet. Again, cheers mate! I look forward to experiencing YOUR journey via your awesome videos.
I think discs from the same production run would be similar (same plastic and moulding conditions), but consistency from run to run is difficult for all manufacturers.
Simon lizotte gave you a shout out on the nick and matt show for helping him learn the lineup. you should reach out to see if you can get a colab with the face of the brand.
I just got my MVP relay and it's almost as stable as my volt but my servo is less stable then the relay and it shouldn't be according to the flight numbers which is nuts to me btw their all neutron plastic and even the same colors.
you should make a video on the prism pyros! those look cool. pretty sure prism just means proton overmold. Ive seen a prism proton, prism neutron, prism plasma so far
Good stuff. I've always thought the plastic stablity talk was complete nonsense. Just an echo chamber with no real proof, "glow is more stable because of the additive" complete bollocks.
Dude... the sounds you played were way too loud. A little warning would be nice as it blew my ears off in my headphones. Overall, great info and thanks.
Sorry bout that. Have made the adjustment in more recent videos. Strangely, the volume in dB's is the same as the rest of the video but it has more mixed frequencies so I guess that's why it seems louder.
@@DiscGolfDownUnder Thank you and I just also want to say your channel is awesome: keep up the awesome work. I’m also working on just sticking with MVP and the information you provide is top-notch!
From what I understand the harder plastics have a different coefficient of thermal expansion. Some types of plastic also melt at a higher temperature. So this all affects the amount of shrinkage on the disc.
Could you show your work please? What's that? You can't because you used your paper for rolling doobies? That's too bad... lemme see that thing for a sec... 😤....🤪....word.
It's pretty common knowledge that Eclipse discs are more OS than most plastics for the same disc. Try an Eclipse 2.0 Insanity, a Neutron Insanity and a Lots/Saint/Escape; you'll realise the Eclipse Insanity is closer to the other moulds than the Neutron version.
Just watched @TheNickMattShow and was stunned to hear @simonlizotte5274 giving me a shout out for my videos on @mvpdiscsports discs. Would love to do a collab with Simon in future.
Simon Lizotte just gave a shout out to DGDU on the Nick and Matt show. He said he watched your videos to learn about MVP discs during his transition to Team MVP.
Just watched the show and was amazed to hear. Thanks Simon for the shout out and kind words. Maybe we can do a collab one day soon.
This is the best explanation of the manufacturing process, coupled with the plastics shrinkage and it's effect on the finishing shape, that can be found!

Cosmic neutron should be a plastic category as well due to the fact they are made with a slightly different blend of plastic. Cosmic neutron tends to be one of their most overstable blends of plastic. Love the vid, wish everyone was this dedicated.🐐
I've found that to be the case too. However MVP say that Neutron and Cosmic Neutron should be the same and technically they should be.
@@DiscGolfDownUnder they're full of it. My comsic Reactor is way more stable than my neutron.
My cosmic neutron Tesla is alsmost as beefy as my neutron terra.
I've found the same. Cosmic Neutron is a LOT more stable then Neutron.

Whoa.. That Neutron Envy is an anomaly. Flies more like a Proxy than an Envy. I have a few un-thrown neutron envy's that I'll need to test out. I've always just bagged the old soft neutron ones.
This is exactly what we needed!
I tried to do this experiment myself a few weeks ago but I realized I'm not consistent enough because one throw eclipse would go dead straight and then next throw it'd fade hard.
Surprised to see soft neutron more OS than regular neutron. I have uplinks in both and the soft neutron is noticably more undestable. Might have to dig my soft neutron and prism envy's out of my backup bin!
All of my old Soft Neutrons are super beefy. But I've heard a lot of people repeat what you've found. My new Soft Neutron Envy showed that also.
I was honestly surprised that people figured the plasma plastic would be near the least stable. I've got a plasma envy in my bag that started out as an absolute beefcake. The thing flew like a glidier overstable zone when I first got it, or what you might imagine a brand new, domey, 175g champion pig would fly like if they made those. I had an electron envy and had thrown new neutron and eclipse envies, and they were nothing like it. Neutral flyers, very mild low speed fade. Maybe my envy is an outlier, but the thing is still reliably overstable even 5 months of throwing it later. Not one single hint of turn out of the thing even now, even throwing it 300+ ft.
Same plasma envy is beef, I’ve heard it more stable for putters but drivers in plasma are less stable
It was really crazy to watch the different flight of each one in the flight test part, and this had the best explanation for why different plastics in the same mold *should* fly differently that I've seen, even if that's not necessarily how it worked out when they were thrown.
I think the video does hold some clues for why the final ranking ended up as it did. Besides the eclipse plastic, which you point out is more rigid because of the glow filler, it seems like the flight test stability results follow the total height on the chart at 16:31 more than they follow the putting line height, at least where the mold is the exact same. And, maybe the reason the eclipse plastic defies this is in its much higher rigidity in the air...it likely holds its form better than the other plastics, preventing any bend in form at the leading edge of the disc when it fights through the air. I could imagine (having never seen it tested) a slight natural "buckling" of the front of the disc as it flies and spins, dropping the putting line height slightly and reducing the stability.
A wonderful and succinct review of this topic! Impressive execution in this brief format. I bet an extensive review could be hours long with a lot more money and time invested. Which I’m not suggesting! This did the job, it’s just an insanely complicated topic
Because of course there is a difference between high speed stability and low speed fade, the difference with drivers and putters, sometimes the colors make a difference and sometimes they don’t, domey vs. flat-top discs, the dynamic effects of wear, temperature, etc. … the list is too long. Darn, it’s an expensive hobby 😅
I enjoyed this content. This is why I primarily just stick to one just one plastic (proton) for most of my MVP/Axiom discs.
Very cool video. I recently swapped out my Eclipse 2.0 Envy out for a pretty new Electron Firm Envy (I live in Oregon and it's wet this time of year). Kept throwing it into the weeds on the right because it's so much less stable. So now I've swapped to my lab 2nd Electron Entropy (very beat in), and it's money.
I think part of the issue when ranking stability of plastic is each run seems to be entirely different. I have an old proton envy that will finish as hard as any tactic I throw. (500+ thrower for reference)
100% agree. I think it's impossible to get reliable data between the plastics until the runs get more consistent. I have a soft neutron Envy from the recent run and it's soooo beef. More than any other plastic I've thrown (thrown all except prism). I love it though.
@@videforslin prism envy’s are incredible like a beat in envy out of box
great work. The community thanks you.
Thanks for you work. I agree with the Prism being more OS than Eclipse, but I love my Prism Plasma Envy for that. I was shocked that Neutron was so flippy. From what I have thrown, it seems like Plasma is more understable. As for Fission, it can be whatever you want as it will hold any line.
I have envy/proxy in every plastic. Just got the prism envy and it's great. Now... czn we get a prism proxy please??
My Eclipse Envy is more overstable than my Prism Envy. It must get down to the individual disc.
Amazing job on the experiment BTW. Biggest issue is that neutron is a lab second. Could be rejected as a startup or something causing the thing to be different. Buuuut I wonder if indeed the biggest driver of stability change is lot to lot rather than plastic to plastic. Probably just need to measure the population instead of just a sample. 🧑🔬
This really shows why pros care so much about runs and say if you find a disc you really like buy 10 more of the same run.
The neutron finding surprised me. Were you able to replicate that understable flight in a regular neutron envy and not just the lab second neutron envy?
My regular Neutron Envy is not that understable but it's also a much older disc from the same time frame as my Soft Neutron Envy which was pure beef when I first got it.
Is lab second not supposed to fly the same?
Thank you for the video!
I feel as though the argument of different colors of the same disc in the same plastic should be at least considered, or perhaps would lead to an easier experiment. That or needing to increase the sample size of each different plastic, i.e. perhaps 10 of each plastic.
I think a lot has to do with air friction as well as spin put on the disc which is up to the player based on grip
I bag an Envy and Proxy, but they're both electron firm. I bag two Insanity, fission and cosmic neutron Insanity. The cosmic neutron is significantly more over stable than the fission. I bag a neutron Crave and a fission, and the neutron is slightly more overstable than the fission, same with the Reactor in the same plastics. On a related note, I absolutely love the fission plastic. Love love it.
Fission is the best.
In my experience both plasma and eclipse beat in quite quick, although they start most overstable. I've thrown atom, mayhem, octane and matrix in multiple plastics and proton is the most consistent to flight numbers, neutron is slightly more stable but perhaps wears a bit faster. Never seen an overstable electron disc. To me it makes a lot of sense. Especially if prototyping is done with proton.
Any chance of doing this same with the volt? I wonder if the driver is more effected by the plastic change.
If I was to repeat this with another disc it would be the Volt. I've got it in Plasma, Proton, Cosmic Neutron and Fission. However, the Comic Neutron is one of the most stable discs I've ever thrown and nothing like the numbers.
@@DiscGolfDownUnder any experience with the electron? I ask because the flight number change to the electron is more drastic than the envy going from -.5 and 2 to a -2 and 1.5
I have a Cosmic Neutron, Proton, and Electron Volt all max or near max weight.
Cosmic Neutron = total beefcake
Proton = overstable
Electron = straight stable but beats in fast and then is very accurate to the adjusted electron’s flight numbers.
Can this experiment be run again with the Hex or Crave or even a Proxy to see if the experimented stability differences you perceived on the envy hold true to another mold?
Definitely want to look more into this but have quite a few other videos I want to do first.
The more I throw MVP, the more I doubt the standard common beliefs in ranking of plastics stability. I believe the differences are not as large as single mold discs because the outer rim is the same plastic regardless of the inner plastic (except for prism and maybe electron?) I think the thickness of the rim compared to the plastic in the inner core also plays a factor in the shrinkage of the rim. When i use the plastics in Streamline single mold discs, I notice a much more dramatic difference in stability between plastic types. For example, the proton Jet is much more stable than the neutron Jet.
For me it was this (most stable to under)
Plasma/prism plasma.
Eclipse
Proton
Nuetron
Electron.
I've come to the same conclusion myself. You just have to try different plastics for every mold. My proton Crave is very flippy, while my proton Volt is a beefcake, f ex. I can slide my fission Wave's edge beneath my plasma Wave's edge when comparing side by side. They're not the same disc at all.
Agree. I've got a Neutron Volt that is so beefy and a Plasma Volt that flips over with ease.
Would angle-of attack, or the angle of both the bottom leading edge and the top leading edge (vs flat) be a useful measurement? Your most overstable disc appeared to have a 'hump' on top that lead to a blunter (or more vertical) top face and the bottom wing edge (below the parting line) appeared to be blunter as well. Of course, the photo angle and color may be affecting my perception. Thoughts?
I looked at lots of different measurements but I couldn't spot a pattern in any of it. I think there's just too many variables in how disc flies including the plastic and also how much it is beaten in. If they were all the same plastic and level of wear I think it would be easier to compare geometrically.
Great video! 👌🏻
I'd be interested to see how Fission plastic fits in this stability spectrum. Some anecdotes suggest that Fission is more stable than the numbers suggest.
I'm slowly adding to my Fission collection with plans to look at this. Stay tuned.
11:00 Asking for the engagement boost for the video, and because I am really curious... in your test you discarded 20% of the throws for being "bad throws." Generally, during play, do you find that to be the going rate? One bad throw in five?
Depends on the day. Some days I can have a round where everything is almost perfect and other days you just wish I'd never gotten out of bed. I find that during these types of review videos that I do get tired the more I throw and the percentage of bad throws goes up at the end, to the point where I say that's enough, time to go home.
Great video mate!
Please do more of these with other MVP discs =)
Shoud the Prism realy be different becuse of the rim plastic? Other than the rim being Proton its no difference from a regular Proton, Neutron or Plasma?
That's a good point. Hoping to do get out and do more but struggling with a shoulder injury at the moment.
@@DiscGolfDownUnder Thanks for the reply! I wish you a speedy recovery. I just found drjeremysteel and disc golf strong here on youtube and it was just perfect for me. Maybe they can help you too. Good luck!
Is it possible that a softer plastic will allow the disc to flex more when spinning, and change the stability?
I'm certain that the Glitch has enough flex that it's shape changes in flight due to aerodynamic pressure. My guess is it increases in stability the faster it is thrown but it's only a theory.
I just did the same thing with the crave and virus.
Virus- proton understable will stay going right, neutron - more stable will fight back
Impulse neutron way understable
Crave- proton understable, neutron- stable, plasma overstable
I throw the crave about 330 as a max and mainly around 275-300
The shape of the disc in flight should be considered, a pliable or gummy disc when thrown may have a different shape in flight than when it is static. I have found that gummy discs with OS molds will be more overstable and understable molds more understable. In my opinion this is due the centrifugal force causing the parting line to deform either up on OS and down on US molds (gummy molds in winter flying more or less stable would be a good test). The dome of the disc in flight will have similar effect due to the lift and centrifigual force on the disc. The other variable that can be considered is the grip of the disc and how it may create more spin based on the tacky plastic. Last variable I can think of is the pliability of the disc causing off axis torque.
There are so many variables and I'd love to explore them all. Hopefully MVP will learn heaps when they get their disc throwing robot up and running. Would love to be on that project.
What about Fission plastic?
Yes I get it’s lighter but what if I bought a 175G fission HEX where would that line up in stability?
Does anybody have an answer?
My experience with Fission is that it beats in faster than Neutron or Proton. Max weight usually starts out more overstable but quickly evolves to something more flippy.
We’re these discs from in house manufacturing? If not it may be good time to revisit this.
thanks for this viddy mate
This was a fun one. I think how domy the disc is changes the parting line height. The under stable envy looked domier, which would make the effective PLH lower.
You might have missed it but I also measured the disc height and calculated the parting line height as a percentage of the total height which takes into account the dominess. I think there was one Envy which was more domey than the others. I tried to see if either measurement method worked but they didn't.
@@DiscGolfDownUnder 🤯
I love envy’s and insanity’s.
I can tell you these two molds are different.
Prison Envy - OverStable
Prison Insanity - Flippy
Eclipse 2.0 Envy - Stable
Eclipse 2.0 Insanity - OverStable++
Plasma Envy - OverStable
Plasma Insanity - Stable
Plasma Insanity - Stable
"Out of the box" stability vs. "After three rounds" stability. The more rounds you play with those discs, the more you'll see it line up with fan reviews.
Best throwing putter is The Discraft Luna and you know it’s true
Based on the video content I would say if you want more stable get eclipse. If you want less stable get electron.
That's generally the case but the order in between is not as clear cut.
Well that sucks! Perhaps you can try this with Streamline? And the big names, incl Innova, while you're at it.
This was the reason I switched from Innova to MVP. It was the old every Destroyer is different. I must have spent hundreds of dollars trying to find another Destroyer just like the one I lost.
It’s really all about “runs” like he described in this video. Manufactures switch up blends, pros ask for certain characteristics, different plastic types etc.
If you find a holy disc, go back and buy five more of that run
i also feel like the answers would change a bit after being broken in, but no real way to test that reliably
I already knew prism is most overstable purely based on the density of the rim. The compact blend to make the plastic means only the biggest arms can turn for example, the prism tesla.
what about the flexibility of the plastic? more flexible may yield more off axis torque and more understable flight.
another thought, look at not just the parting line but the curvature of the top of the disc. a flat top will have more upward torque and therefore overstable flight. domey top has more torque on the top front of the disc causing the understable flight.
anecdotally, my neutron hex is surprisingly over stable. so maybe it's mold dependent and there are other variable too.
I agree about the flexibility, it tends to be an overlooked aspect in these plastic stability videos. But the effect of dome is known to vary with the mold, domey discs tend to glide straighter, so flat discs can be on either side of that.
Great video and thanks for the effort. Based on my experience, your experience and THIS experiment I would hypothesize that you could stand at the end of the production line for a given mold in a given plastic, go to the field and throw them, and be just as surprised with those results as we all were with the results you brought us in this video. End point: You gotta hunt/find the disc YOU need in a given mold taking into account the available plastics ... great for the disc manufacturers ($$$), not so great for us. :) Cheers! Love your channel!!!
Given that MVP because of the overmold produces discs with two different plastic types I would also hypothesize that this exacerbates the confusion ... Still, I throw MVP. I love MVP and will continue to do so. Luckily for ME, part of the fun of disc golf is buying/trying new molds, old molds in different plastics, going to the field and seeing how they fly. Then building my bag to better my game on the course. It's a journey and I SO love THIS journey. Also, I have never met a person on the disc golf course that I didn't get on with swimmingly, thus I theorize that the disc golf community is filled with some of the best people on the planet. Again, cheers mate! I look forward to experiencing YOUR journey via your awesome videos.
I think discs from the same production run would be similar (same plastic and moulding conditions), but consistency from run to run is difficult for all manufacturers.
what is a star gazer fish?
Lol, your neutron Envy is broken or something. I've never had it fly like that thrown flat at 200ft. That is bizarre
Yeah I think so too. My beat in Neutron Envy is nothing like that but it's also a much older disc. Maybe a different mould.
Some explanation can be found in the fact that he was throwing into a left to right headwind.
Simon lizotte gave you a shout out on the nick and matt show for helping him learn the lineup. you should reach out to see if you can get a colab with the face of the brand.
Here is my question now, with a more blunt edge, would the cooling of plastics effect a putter shoulder different than the wing of a Photon
Weird, my Prism Envy is one of my least stable. It just flies straight with a small finish. My Eclipse Envy is almost as stable as my Stabilizer.
As if I wasn't already confused now I'm just 🤯
Simon sent me. 😅
I just got my MVP relay and it's almost as stable as my volt but my servo is less stable then the relay and it shouldn't be according to the flight numbers which is nuts to me btw their all neutron plastic and even the same colors.

you should make a video on the prism pyros! those look cool. pretty sure prism just means proton overmold. Ive seen a prism proton, prism neutron, prism plasma so far
2:04 early highlight
Good stuff. I've always thought the plastic stablity talk was complete nonsense. Just an echo chamber with no real proof, "glow is more stable because of the additive" complete bollocks.
Dude... the sounds you played were way too loud. A little warning would be nice as it blew my ears off in my headphones. Overall, great info and thanks.
Sorry bout that. Have made the adjustment in more recent videos. Strangely, the volume in dB's is the same as the rest of the video but it has more mixed frequencies so I guess that's why it seems louder.
@@DiscGolfDownUnder Thank you and I just also want to say your channel is awesome: keep up the awesome work. I’m also working on just sticking with MVP and the information you provide is top-notch!
Geez why can’t Innova just make consistent molds!? Every other manufacturer is so much more predictable 🤣
It might only matter more for higher speeds since its exaggerated
My Plasma is much more overstable than my prism. Maybe mine is a fluke
Same weight?
@@DiscGolfDownUnder prism 174 plasma 172
I won't be satisfied until an ANOVA DOE is done on all variables affecting stability. 🤣
I wish I had the money and resources to do that.
what is the opposite of subscribe
Let me save everyone the time and tell them that the harder plastic is more stable. Also, the newer the better
I think the stability difference is caused mostly by the different rigidities of the plastics.
From what I understand the harder plastics have a different coefficient of thermal expansion. Some types of plastic also melt at a higher temperature. So this all affects the amount of shrinkage on the disc.
Idk what u smoking but eclipse envy’s r so undersable while prism is more overstable
Could you show your work please? What's that? You can't because you used your paper for rolling doobies? That's too bad... lemme see that thing for a sec... 😤....🤪....word.
@@xAllCatsAreBeautiful1312x rt
It's pretty common knowledge that Eclipse discs are more OS than most plastics for the same disc.
Try an Eclipse 2.0 Insanity, a Neutron Insanity and a Lots/Saint/Escape; you'll realise the Eclipse Insanity is closer to the other moulds than the Neutron version.
you contradict your whole video at the end.... worthless content
