When you say "working ADV" do you mean reachable by the diver or actually working ADV? Working is easy and I'll send some pics to you when I'm on my other machine. (In a day or so)
What is the hard case going to add? I'm not following you here guys?
I have opted for a set of neoprene lungs for my next experiment that I'm waiting on some parts for. It will be a month before I can post pictures for that one.
Steve, with the bmcl you can have the wing when its inflated, and your back pushing against the CLs, reducing available volume, plus even with normal OTS CLs when you breathe out you are having to 'move' the cl cover up and down (more loss) I have found a big difference in wob when the inner bags are totally free to move unrestricted inside their own case....I found neoprene covers to be even worse

Imagine when you breathe out you are moving/lifting the neoprene, or whatever material the covers are made from. I can notice the difference so I suspect its quite high
