I plan on having one of my tanks hydro'd and have a regulator installed by Ninja Paintball. I already have two high pressure tanks/regs for my Mags. I want a low pressure tank to run my Tribals and Angels. I know the Tribals run on 150 psi coming out of the LPR, and the Angels run on 60 psi (for 05 Speed's) and 100 psi (for LCD's) coming out of the LPR. Now, correct me if I am wrong, but if I make the output pressure of the tank reg too low, the HPR's on the Tribals and Angels will regulate that pressure down even further, so by the time it gets to the LPR, it will be so low it may be unusable...? Or, would I be able to order a reg with a 300 psi output, and make adjustments at the HPR? Any advice?
