I dive with 6-8lbs of lead. when I did my OW course i was told that I needed about 10% of my weight in lead. I know now that, that is wronge, because i don't need that much. My question is how much weight do you guys use? i am 5'10" 230lbs and in a full 5mm wet suit i use 8lbs. ( where did the abbr. for pounds come from there is no l or b in that word?)
