Obviously not a recommendation. But.. steels are regularly seen overpressed to like 240+... alu... EEK! look athe materials data and you'll lose ANY desire to OP an alu tank.

Bill R gave me a few 250bar O2 fills in NF few weeks back goto love cave divers and their fills

Personaly I have a rule: as soon as I start thinking I need to push up the tank pressures on bail gas to get the volumes needed I KNOW im cutting it too fine and need to take more tanks! Yes I do overfill (not much if AL) but I look at it as 'extra' gas ie its not counted in my bail out calcs.
