Steve, I usually dive with an AL40s (6L) for my stages. The 50/50 is of course at 200 bar (due to air topping) and my O2 bottle is usually around 130 bar (since that is the max pressure of my cascade) This is about 26 Cu Ft of gas (minimum 520 L) this is more than enough gas for two dives. Plan the dive using the right gases. If you do not hav enough, scale the dive plan back. Perhaps one of these days we can go for a dive together. In a few years I will be making the move to Australia (Sydney). The state are driving me crazy.....
