I decided not to post of the recent Eagles Nest accident thread as really this isn't about that but might help some people with stuff they might not get to try for themselves. Maybe others can add interesting factoids.
I dive a JJ. It is easily 10kg, maybe 12kg, negative with the standard SS backplate and steel cylinders. Maybe with aluminium cylinders and backplate that might be 6kg.
I'd never contemplate taking it off underwater wearing a drysuit.
I have dived in a flooded drysuit, it doesn't impact buoyancy as much as you might expect. (See Diving Rant for a quantative test). Makes getting out pretty hard though. Oh, and if you think your out of control buoyant ascent wearing a drysuit will be head first and so poking at the neck seal will help you may be disappointed too.
