Are you asking about how they feel underwater, or what is the advertised lift capacity vs the actual lift capacity of each wing and how that differs?
The Mach V is quite a bit narrower than the Hog wing. I don't ever put a lot of air in my wings, but the small amount I do put in I noticed perhaps just a tad more air migrating around in the Hog wing from side to side just based on the width.
The thing about the Mach V is that it is so narrow that yes it keeps the air closer to the center axis of your body because the tubes on each side are closer in. However there is also an inherent design problem with wings that narrow, and that is that when you sandwich an extremely narrow wing between the tank and plate it restricts the inflation capabilities of the wing because of the wedge that the tank and plate create. With the Freedom Plate it's not as bad because there is a section where the plate is narrow so the wing can round out like it's supposed to. The lower section the plate is also curved and has the rail stand that sets the tank off the body so that gives the wing more room too. It's still better than some of the regular doubles plates that don't allow a lot of room anywhere.
I have questioned many times the actual true lift capacity of the Mach V when it is in use set up as a rig. I don't believe that a 30 is actually a full 30 lbs of lift when it's being used, maybe more like 20 something? Really hard to tell.
So my 40# wing might be 32 or 35 when its set up on a plate with a tank, I don't really know.
I suppose there would be a way to test it set up with different plates and different diameter tanks. All the readings would be different.
With the Hog wing being wider the inflation cell has plenty of room to fully inflate so the advertised lift capacity I think is a lot truer to the claims.
