 I have seen those tanks that Walt referred to. Yes they are a smaller size
than a regular steel 74.2, and yes they do hold 80 cu ft @ 6000psi _BUT_
most places that vend air can pump (MAYBE..) to 4500. Most boats have only
2000psi available. This is the reason I purchased a Scubapro steel 96. The
rated cubic displacement is @ 2640psi (that's counting 2400psi working + 10%
overfill which is allowed for the 1st five-years!) With a 2000psi fill the
tank is about 83 cu ft, or so I've been told...maybe I should check this with
some of that fancy math stuff! (-|  The buoyancy factor is -6lbs full/-3lbs
empty by my testing. It seems to be a nice tank. It only cost $275, and while
the that's close to the cost of a Justin Stainless (of Chanute, Kan) Tank
the practical use of a scuba must take into account the available pumping
pressures. One other point-98% of the regulator 1st stages are only rated to
3000psi. If you try to use your regulator with >3000psi, the yoke will let-go!
If the industry goes to 6000psi, I think I'm gonna setup an NC 5-axis to
manufacture 6000psi rated replacement yokes/1st stage cases!!!
