My instructor said 15% of my body weight for a 7mm wet suit with hood, gloves and booties and AL80. That was just about right.

Oops gotta change this...our pool heater quit at the lds last week and dropped from 80 to 74 degrees. Absolutely felt a buoyancy change. Other instructor felt a change as well. We both normally teach with minimal lead. So there can be a slight difference.Not necessary to add lead if cold.. Here in NY I am 5'11 weight 175 and use 16 to 18 lbs of lead in a 7mm wetsuit.
in a DUI cf200 and 400 gram thinsulate I am up to 24 lbs of lead . This is in salt water. Much less in fresh water. Tank can be a HP steel 80 or alum 80. I usually do not bother taking less lead when using steel tank. BCD is a Dive Rite transpac with rec wing bladder.
