Toro 570 options -- what to pick?

I'm wondering what Toro 570 spray head options to pick -- mainly PRX and COM. My situation is that I've got a 400 foot frontage along a street along which I have to plant grass due to HOA rules. (Really stupid in dry California :-( ) The elevation changes about 30 feet along this distance. I've designed in 4 zones, the lowest pressure zone is at 30 psi and the highest is at 40 psi after losses from pipes, valves, etc. from the 60 psi available at the backflow preventer. Will the PRX feature help...
