I just took my daily diver in for a vis and a fill and realized it costs me as much in fuel as it does for the fill. My thought is that it's only a little more expensive to fill my 130s than my the 72, and so if I got them all filled, how maby times could I refill the 72 off the 130s before I had to take thr whole mess back in? The 72 is 2216 psi and the 130s are 3000 psi.
