How much extra lift can you get with your drysuit?  I tried this once.
Achieve neutral bouyancy at the surface, with the drysuit at your
"normal" level of fullness.

Get someone to hand you weights, compensating only with your drysuit,
until the air "burps" up through the neck seal.  I managed 8 kilos.

I don't think I *could* use my drysuit as a primary bouyancy device,
without getting a much tighter neckseal :-)

Except that no-one was talking about having two wings - just a spare

Hmmm.  I think I need more convincing.
