Kevin, if you ever take a set of double 104, you'll be overweighted!  You
don't need any weight on your waist to accomplish that.

Oh... it was already said.  I want to add that it is true even if you dive
with a full dry-suit and underwear.  With my DUI-CF200 and a viking open
cell underwear, I inflate my dive-rite BC to approximately half capacity to
stay neutral.  I did not try with my DUI Thinsulate underwear (the 35-50F one).

This may be true for dives made in Florida, but I would like to die if it
happens in 36 degree water and I have to spend another hour there.  I take a
spare mask on my dives and I often exercise changing mask underwater (as I
exercise any other skills)... this is a PAINFULL experience!  I would not
like to be even five minutes without a mask for anything in the world (in
cold water).

Have a nice day!
