If you haven't gotten a bottle yet, don't go any bigger
than 13 cu ft or so. That size holds enough gas for 8 dives
to 100+ fsw. Anything bigger is just bulk and weight.

Here in Europe we don't work in Cubic feet but work in water capacities and
pressure(ie how much fluid the cylinder could take (defined as Water capacity)
and therfore what is its exact volume) - what this allows us to do is to simply
look at a contents gauge (in bars) and calculate real easy how many cubic
liters of gas we have at any point in the dive - In addition the US system
means that a 13 cu ft cylinder is 13 cu ft of gas at its working pressure and
that as different cylinders have different working pressure its a pain for us
Euro's trying to convert to figures we can realate to - to get round this I
wrote a article for my clubs newsletter which detailed all cylinder cubic feet,
working pressure figures etc etc for the standard US cylinders which allowed us
to relate US cylinders to a water capacity - I did not go down to ponies as I
had no details on the working pressures - therfore could someone provide the
working pressures of these size cylinders and I can update my article
