I was wondering about 1000psi burst discs the other day. Theoretically it should be ok, but you do risk loosing all your gas on a hot day whereas with a relief valve it just dumps enough gas for the pressure to drop to below 1000psi.

Somthing like a 1200psi burst disc would probably be more useable but that would mean a change in the gas pressure rules which I imagine is very unlikley to happen.

Alan: I assume your burst disc idea is to have one inline with the pneumatic system like the relief valve and not replacing the one on the bottle ?
