You die like Parker did. We don't take our tanks off. Actaully, Parker
took his off and dragged them next to him to hold him down, and then
blacked out and blew to the ceiling when he cleared the restriction.

I have found you can not move forward very well agsinst a ceiling with
the tanks off in a drysuit unless there is plenty of room to push
yourself down, which means you do not need to take the tanks off. We
just do not do it. 

To weight ourselves with 22 additional pounds required to offset the
drysuit with C-4 would mean wings blown up like a Zodiac, and drag that
would be impossible. We rig for speed. Also, weightbelts on a drysuit ,
unless harness rigged with suspenders, are a nightmare, and again, we
rig for the real risks, not the phantom ghoasts in the closet. I make my
bet before I get in the water, and did so that day, and will continue to
bet that way or not dive. 

This is like the "how do you do your deco if a shark bites of the hand
with the bottom timer?" question. The answer is the same - "you don't".
