Has anyone experimented with meter pipe pressures? I use 90psi because that is what was recomended to me. The reason I brought this up is that I want to shorten my meter pipe so I don't bump it as often. I can shorten it by increasing the diameter but have to drop the pressure to 55psi. Is there a real world difference in performance or not?

Crowley, you took the words right out of my mouth. It's a shame you can't be banned for shear stupidity...
