I really don't worry about diaphragms being a switch problem, and I really
do not plan on switching anyway, other than the second stage ( we leave them
finger tight for that reason). Most of the problems other than broken hose
can be overcome by turning the valve off and on.

Landon indicates that he has had problems with blowing out the diaphragm,
but I never have had it happen. I can not see it happening if you have the
second stage button pushed when you turn on the valve to clear any water.

At deco is really the only place you want to stop and play with reg
switching. I use almost all DIN anyway, and that solves the main problem
that cause the need to switch regs anyway.

Oceanic makes a good piston reg that looks like a MK 20 only you can adjust
it and it is half the price. I have a few of those.

Like I said before, I have no Apeks or Oceanic parts. Last time I blew an
Oceanic, I merely cleaned off the seat and put it back together. Last time I
blew an Apeks ( got sand in it ), I took out the seat, rubbed it with emory
cloth, and put it back in.

Last time I had to fix a Scuba Pro, which is every week, it cost me 40 bucks
each and the annoyance.

The problem is finding a good replacement for the mk20 G250 combo.
Since you don't want a diaphragm reg on a stage, in case you have to
swap regs and flood the first, what can you do?  I love my Apeks for
backgas, and being able to get the service kits is great.  I don't
even dare open up the mk20, I have no parts, you need special tools,
blah blah blah.  Anyway, Trey, if you know something else that works
well, let us know.

Cheers.
