Spend the extra dough to buy a Reduced Pressure PVB, then you can use the "regular pressure" heads.

RVLI has a good idea, but are all your zones sprays???? You dont want reduced water flow and presswure if you have a zone of water. If you have abnormal pressure (i have about 80-105 psi) i install numerous amounts of heads ont he line. That way the pressure evens out. If you have a zone of sprays with 3-5 sprays then i would spend the money for the sprinkler head PRX.

Also run as many as you can with the GPM, if you really dont want to spend the money than you can buy regular heads anyway

If you are worried about the pressure being too high cant you just design your system with higher gpm nozzles and this will reduce the pressure. It is simple physics increase flow and lower pressure.

Yes, but the higher the flow also means the further the distance. I would buy regular heads and install the max amount for your gpm and you will be FINE!!
