For me it wasn't about drag but about reducing clutter. My modified wing is bungied tightly, has no hoses (one less failure point on whichever reg) and can barely be seen when I'm wearing it, even with the mini-cylinder. But should my suit rip at depth, I have 25kg of buoyancy available which can easily be dumped during ascent allowing deco to take place no problems. Without having to dump any weight or gas or expensive toys, or experiencing a runaway ascent.
So I suppose it's about reducing the wing from a primary buoyancy device to an emergency buoyancy device, thus removing clutter and failure points. Works for me.
