Wow! I think that was the most spirited discussion I have seen on dive buddy. Can’t resist to throw my two cents in after some of the bubbles have disipated. I’m a recreational dry suit diver and as I was instructed by PADI in their specialty course, I use the suit for below surface bouyancy control. As a recreational diver, I carry substantially more weight to offset the additional bouyance provided by the suit, but after I have eliminated the squeeze by adding air to the suit, I don’t need any more positive bouyancy. For me, the air in the suit is just enough to maintain neutral bouyancy at recreational depths-no need to inflate the BC. With the drysuit inflated then, I manage position of the bubble in the suit to attain my desired body position. A stuck inflater valve would be managed by disconnecting the inflater hose.
