First and foremost, love the channel and all the content, good job. That out of the way, allow me to play devil's advocate a bit. Not all wings maintain their profile the same while creating the same amount of lift. Related, your example diver between 0:40 and 0:47 has a lot of lift from the drysuit (the shoulders and arms are fully inflated.) I think the comparison needs to be made between different exposure suits, i.e. dry vs wet, and also full vs empty cylinders to make a definitive statement between this wing or that and whether or not all wings are suitable to all diving environments.
