Hunter nozzle for Hunter I-20

I am new to sprinkler design and would appreciate any help that I can get selecting the proper nozzle for the Hunter I-20 rotor.

I have a design that requires 6 rotors. Originally I wanted to use Orbit Voyager II, but a local dealer talked me into Hunter, because of its superior quality. I have 1 full circle, 2 1/4 circles and 3 1/2 circles.
For the Orbit rotor, I was told to use nozzle #2 for the 1/4 circle, #4 for the 1/2 and #6 for the full circle to keep my precipitaion rate the same.
My main line is 3/4, my meter size is 5/8 and my pressure is 65 PSI. So I believe that gives me about 15 GPM total. For those 6 Hunter I-20 rotors, I need to know waht is the proper nozzle to use on each (full, 1/4 and 1/2) so that I don't exceed 13 GPM

15 gpm is pushing a little to much water for your set up. You would be much better designing for 10 gpm.

OK
I will re-think the nozzles aroung 10 GPM
I also wanted to change to the Hunter PGP rotor for economical reaons only.
Am I risking anything?
