You know, the really funny thing about this post is that while it sounds
like a joke, it is absolutely right; the "good old boys club" is the
easiest, most cost effective way to cut through the bullshit.

We've got a dive shop a ways from here that has mild techie pretensions,
Northeast Divers near Boston. If I am to believe what I hear, they are
routinely doing overfills for half the divers I run into. But when I
stopped in, on a trip down that way, with a couple LP steels, and asked the
girl if she could run them up to a modest 3000 psi, she gave me a filthy
look as if I'd just asked her to palpate my hemorrhoids, and launched into
a prim little lecture about the evils of overfilling and how "we don't to
that here". OK, I guess they have a right to save the good treatment for
regulars, but I wish they'd spare the rest of us the outraged act.

Though why a cascade? You don't need for nitrox, and a booster makes more
sense for trimix. The only thing you really need a cascade for is mixing on
a grand scale, or bottling 80%+, and even then the cascade isn't going to
get you  reliably much over 2000 psi.
