What size is good for doubles?

[Don Burke]

Thank you Don Burke...
The guy who´s selling them said it was because of backproblems so you make a good point.
Still...getting the doubles for 375$ (incl bands and whatnot) is a convincing argument all of its own...

There is always the option of using the 15 liter tanks as singles and using the bands and manifold on a smaller pair of tanks ...

Since all of this stuff gets taken apart for inspections anyway, mixing and matching is an option.

I have two 112 cubic foot tanks that I bought with thoughts of doubling. The manifold is on a set of 72s and bands are in the drawer. I can always try them doubled if the mood hits me.

I have a 72cft right now (300 BAR)...
buying another one for 2 "double sets" isnt a bad idea...
They´ll propably be enough for me in the 90-120 ft range while wreckdiving (even if I can only get them up to 200 BAR...

Food for thought...Oh, and who said scuba was an expensive sport?! duh...
