Which Hunter rotors to use, PGP or PGP-Ultra
I'm preparing to have an irrigation system installed at my residence in Florida. With my research, I've decided to go with Hunter. The contractor I'm leaning towards turns out uses Hunter. I would like to know if it is worth the (I assume) extra money to go with PGP Ultra instead of the recommended PGP? I have similar questions in the Valves and Controllers forums. Thanks, Gary
