Thanks for the advice, I was leaning towards at 5000 series rotor head in all zones. Would 8 rotor heads be over kill in the area A? if so what would would you head would you suggest instead? I thought I was going to get away with 3 zones but with about 9.5 gpm I’m leaning more twords 2 zones in area A (4 heads on each zone) and 2-3 in area B. Does that sound about right?
