An aluminium 80 cylinder is roughly 2 lbs negative when full. This is the amount he should use for the calculation not 5 lbs of air.

You do not need to carry all the weight on your belt. Also check out rubber weight belts, they are much better than the nylon belts. Also a DUI weight harness may be a thought.
Thanks for catching my error, ams511! Yep, about 2 lbs. negative, not 5 lbs. like I posted.
I actually knew that; it once again reminds me I should refrain from posting when I'm tired, coffee-deprived, or otherwise brain-dead

Well, the brain-dead part means I would never post....
Carry on with the discussion

Best wishes.
