JD, I think your ideas are appropriate for open water, single tank diving. I strongly disaggree with using the drysuit as one's primary bouyancy control while cave diving, or while wearing multiple tanks. Inadvertant changes in profile brought about by changes in current, task requirements, emergency procedures, or passageway configuration can lead to catastrophic bouyancy problems when using the dry suit to support the weight of doubles, stage bottles, and canister lights. Rapid, fingertip bouyancy control by the diver and his potential rescuer are a must in unfriedly environments. My single set of wings meets this criterion better than my partially opened tls drysuit valve, even when I am trimmed out perfectlyt. This does not even address the problems assosciated with dumping one's precious argon with changes in depth. Best of luck. Keep your feet down!
