Bob,
I`m 6 ft , 250 lbs, in a 7 mm farmer John WS I wear 18 lbs. (aluminum 80, aluminum BP& wing)
In my viking HD (similar thickness to your 1.5 mm compressed neoprene, I wear 25 lbs = 7 lbs added.
I`m wearing Bare polar extreme underwear in my drysuit.
As previously noted you should start your dive about 5-6 lbs over weight, to account the loss of air mass from the tank throug out the dive.
regards
Mike Dolson
