Now don't get upset WreckWriter. I didn't mean to hang on it instead of using good bouyancy, but rather to use it for deco and if you or your buddy are having any problems it would be in your best interest for a bag with plenty of lift should it be needed. I also agree with cyklon_300 that the Halcyon 60lb bag is plenty. Our local tech instructor also uses a 100lb carter lift bag, but he doesn't have a problem if you want to talk to him about changing a little. It is all a matter of preferance. Anything from 60lbs to 100lbs is enough. I hope that I didn't confuse anyone. Sorry
