Pro 120 cu ft of gas vs 77 cu ft.
Con for the 120 is that some shops don't fill to the full 3400 to 3500 .
I'm a big guy, jus' under 6' 3", and was thinking that when I get My tanks I'd go with the 120's , but this comment about 120's being shortchanged on air fills rankles me a bit... or maybe it doesnt...
It all depends on how the fill is being Charged, when you get charged to fill your tank are you charged based on its size? (80, 100, 120) or are you charged for the amount of Actual Air that goes into the tank?
If its the former, I'd be being cheated as I'm Paying for a 120 fill and not getting a Fill; if its the Later then it doesnt matter in the slightest...
Another question is Why dont they fill it all the way? are there diving or other safety concerns? I mean either the tank is rated to contain a certain psi or its not, why cheat yourself outta extra dive time?
