Subject: Re: Fw: cylinders-BC's etc
When I drop my weight, I can indeed float. When I am using steel, I have
a drysuit on. In either event, the whole rig gets dropped if that is
what it takes, but the eighties float.

Robert - why are we talking about the surface? Let's talk about at the
bottom, when I need to get up. I do the same - drop my weight, or use
the drysuit if the wings fail. 

Let's go even further - back to the boat : why do we not have a balanced
rig in the first place?
