BP/W with weight belt

[nimoh]

That's not too surprising. When I dive dry in 60 degree water, single AL80 and aluminum BP I only use 16 lbs.

me too, sort of. Steel backplate (6lbs), single tank adapter weight (6lbs), 4lbs in cam band pockets.

I know quite a few people that are about the same size as me, use double the weight and are so sure that they need that much weight that they aren't willing to do a proper weight check at the end of the dive, or are unable to get enough gas out of the drysuit or BC during the weight check.
