After measuring my yard I will need roughly 44 rotors and 15 sprays to do the job. I am installing a sprinkler system on 3 sides of my house and watering about 60 feet in depth on all 3 sides. My well head is on the side of my house so I think I may tap into the line there and run both ways to limit the water travel. My deep well is set at 68/48 psi and my dry and wet test show me at about 12gpm. I think I am going to use the Hunter PGB rotors and try for about a 30' spacing on the 44 rotors. I have several Optima UCR-1 pop up rotor heads I purchased a few years back and never installed them. They are pretty big and look to be commercial grade. I have 20 of them. They have a 3/4 inch female inlet and at 35 psi use 3.5 gpm. At 3.5 gpm I can only get about 4 of them on a zone. That's a lot of zones? should I ditch the Optimas or ?
Not sure what to say about the optimas but you will probably be able to get 6 heads per zone with the hunters. That will still work out to be 7 to 8 zones. May be try to ebay the optimas.

With the amoutnt of gpm you are getting you will be able to run 6 Rain Bird 5000 Or a comparable hunter head. This should cut down on your zones. Make sure to use head to head coverage and space the 5000 about 29-30 feet apart.
