High pressure systems can be more prone to leaks, put stress on the
needle valve, and may have the dreaded tank end dump. There are many
horror stories on these forums and APD about tank end dumps. It happed
to me twice using Dave Gombergs regulator before he added a needle
valve to it.

So it was the design of the set up, not the regulator itself. Not
having a needle valve is the main issue, not the regulator for the end
of tank dumps and also dumps were the seating on the Ehiem disc gets
loose or the disc gets clogged good, backs up and then blows out lots
of CO2 real fast.

I've been using clippards and beer reg's for over a decade now. Never
any issues, dropped the gas tanks down to zero psi many times over the
years.
