Frank,

It doesn't need to be a derisive issue at all. The facts are simple, the only way it becomes derisive is by some that are all too willing to ignore obvious facts and misdirect the issue for their own agenda.

Let's look at the design of a wing, it is designed using basic engineering priniples. If you wanted to suspend something to float in the water such as a Zodiac boat, would you want the air up and the weight down? Or would you want weight up and air down? Naturally you'd want air up and weight down. That is the design of a wing. It is also designed to compliment the tanks, meaning that the design is aerodynamically complimenting of the configuration. This results in minimial amount of additional drag, and significantly less dynamically instable air. If a diver uses his drysuit as the primary inflation source he significantly increases the amount of dynamically instable air source resulting in poor balance and adverse consequences realting to bouyancy issues. The idea is to reduce the size of the instability and use the design of the wing to minimize the area. Any more air in your suit then the amount needed to re-establish the loft in your undrgarment is a waste.

BTW, now you know why jacket style BC are less efficient then BP & wing designes.
