Not to try to claim bondage wings are GOOD, but on this point I think there may be some (valid) alternate views. Ok, so bondage would keep wings close to body, even when inflated, more along the plane of the body, and you claim present a larger forward swimming profile, equalling more resistance.... Other wings will wrap up around the tank, providing (as you claim) less of a forward swimming profile. first I must say I am not convinced about the profile. As long as the air is disrtibuted within the wings, and doesn't tend to collect at the top (defined as closer to the diver's head) in one style more than the other I can't see how wrapping around a tank accomplishes the magic trick of providing the same bouyancy in less space. Second, it would seem to me that as your wings wrap around your tank it moves the bouyancy moment (I use the term loosely) farther away from your own center... ie it would seem to me that the circumference of the diver as a resistive force in the way has now increased. Just as you want your weights close to your body I would think you'd want your bouyancy close to your body. We wouldn't put weights on the back of our tanks as they tend to want to flip us over... if we put bouyancy closer to the back of our tanks, it seems like that makes it harder to flip over when we want to, or to even turn sideways when going thru a restriction. Again, leave out the other arguments about bondage wings, if you want to disagree, just lets discuss this one point?
