I have a balanced (singles) rig and don't use ditchable weight. I know I can swim my rig to the surface in case of BC failure, so I feel comfortable not having additional ballast (it's all on my plate). Doubles are another matter. I'm horribly overweighted when I strap those suckers onto my back. Although the sensation isn't so marked in rental Al80s, my steel 100s are something else. I rely on an SMB as a source of redundant lift in open water. It's the DAN SMB, and I think it has 30 lb of lift...that's 12 lb more than my little wing, so it's all I need. Ultimately, I know a drysuit is on the cards for added security when diving doubles...as much as I loathe the idea of wearing Depends undergarments, or experiencing the Divine Secrets of the Ya Ya She-Pee, it's got to be worth it for the redundant buoyancy alone.
I guess I am a little confused here... you say "my little wing...", how little of a wing are you diving with double steel 100's? Depending upon the tank, those puppies mounted on a backplate with full kit of regs, harnesses, knives & other accessories are going to be pretty negative... is your wing too small to float them at the surface at the beginning of a dive? If it is, then that's an "interesting" configuration... and if it isn't, then your wing really isn't "little".
