So, who in Cali is pumping tanks to 3500?

Sure, change your story now, Dave...Let me be clear (I did not read all the way back).
HP steel tanks get filled to that pressure. Many overfill by a few pounds to allow for pressure reduction after cooling.
AL tanks get the same treatment but limited to 3000 psi. No "cave fills" is SoCal, as far as I know.

OK, done. I took both to mean they have the capacity to fill steel tanks rated for 3500 psi, not that they fill every tank to 3500 psi.Check out the bottom of this page for the Peace, which is one great dive boat: About Peace Dive Boat
Or, go to this web page for California Dive Boats and check out the air fill column.

i would expect that the diving industry has settled on the al80 because it is most economical to produce, holds sufficient air for most recreational diving purposes, etc. There are other places on earth where the population hasn't come up to date yet and still use steel tanks and drive on the wrong side of the road, like britain, but that is rare. Al80's seem to suit the rest of the world just fine and will remain to do so probably forever.
