Your gas requirement is based on your RMV, not on anything else. Perhaps you have participated in the poll
Average Gas Consumption
There has been extensive discussion lately regarding average gas consumption. A poll may help give us a better idea of what the normal distribution of RMVs is. 1 cu ft = 28.32 liters 1 liter = 0.035 cu ft 28.3 l/minscubaboard.com
True.
But my tank choice is 100% based on my ability to trim them out.
We go with smaller backgas tanks, and sling more air if needed.
Hp100's are mostly cake. Hp120's may be easier, or worse, to trim and reac the valve. Hp80's are wonderful for short divers with heavy feet.
As for HDG, it's wonderful only if you have a LDS with a decent hydro guy. Nothing is nicer than nearly new tanks failing hydro due to moronic scuba policies.
