130s are the same basic dimensions as 108s, the the 3442psi version. The youngsters are all over them nowadays

With a bit of a fill my 104's become 140's.....

I totally understand that. I love my 108s as well. But for me, doubling up 130s seems a bit much.

I must admit, I don't understand your logic here. Don't both tanks hold basically the same amount of gas at the same pressures? I mean at 3600psi my 108's hold around 147cuft of gas, which if measured at the same temperature as HP130's, I'd bet they would be the exact same or close to it.

For some reason I was thinking the 130s was low pressure. My bad, brain fart.

Ah no, I think you're thinking of LP120's.....those things are beast....

There are lp130 and larger tanks made. They are like submarine ballast tanks though.

HP130s, LP104s, LP108s are basically the same dimensions.
