I think I went through this with George a while ago, and the net effect of
his answer was that you need to be able to take off your gear without being
ridiculously buoyant.  So, I'm shooting for about a 12-lb weightbelt as a
compromise between the least weight on my waist possible and not being able
to take off my gear.

Of course, the dangers of "george said this" are manifold, but that's at
least how I recall it.  Basically, you also need to be wearing enough weight
to offset the buoyancy you will gain as you consume your gas, wherever you
put it.
