Bucking Wood with Vintage McCulloch Pro Mac 10-10 Power Saws

I find bucking a tree, once its downed, takes more thought than felling- or rather its just a different kind of thought process. I know the basic principle is simple, you want to make a cut in the compression wood first, to lower the stored energy inside the limb, then cut the weakened tension wood.
Sounds easy enough, but when i'm moving around a lot and trying to maintain a clear work zone and good footing, and at the same time judging where the tension is in any given limb, or how it, or other limbs- if there are any other limbs touching it- are going to react once cut, seems to require the need to slow down sometimes and think before you get your saw pinched, or get hurt, etc.
Sometimes its hard to assess accurately where the most tension resides in certain situations..so after I've made my best judgement, I just start cutting on it to get a better feel for what the wood wants to do.
I noticed some of the heavier limbs split a bit at the ends, because i didnt make an undercut first to release some of the tension. That was not desirable for what i wanted to do with the wood.
As for my technique, on the part of cutting the main trunk, while obviously quite shitty, was shitty indeed, worked at least well enough to get the log separated without pinching my bar in the process.
I read somewhere that there is a different sequence to cutting big logs, some three or four calculated cuts in certain order, instead of the common two or three cuts you'll ususlly see recommended on smaller limbs.. it says the bottom first, then a side, or some shit, i forgot, ill have to study up and practice some more on that aspect of woodcutting. :)
