lower pressure does not mean less flow - get a varistream and use either a 60 psi/75psi/100psi pump, I keep hearing people on this forum say 100psi is for 2 reels/2 operators etc etc - its nothing to do with that, flow is much more important, ok so using microbore etc will create some backpressure, in which case a 100psi pump will help deliver a little more flow than a 60psi pump will, but on the whole the output is more dependant on the pumps flow rate and what position the varistream dial is set to.
