George, The LP 72s Dave is talking about have very similar buoyancy characteristics to the AL80. If one only needs ~30cf of O2 for deco, why carry the bigger bottle? These old 72s hold ~62cf at 2250psi, sufficient redundancy for that application. They are readily available for less than $50 each. Tell us why these are a bad choice. =Art= At 10:05 PM 3/11/97 -0500, you wrote: > Dear Dave - using steel 72's for oxygen is like hose-stuffing - you do it >because you saw somebody else do it.
