Rotor basics help

Last year I used Toro for my backyard install of all spray heads. This year I'm planing to use rotors such as the Toro Multistream PRN due to a significant slope in my design for the front. and customer service could not find any performance charts!! So I check Rainbird, printed a pefformance chart for their 12SA and I think I understand it based on all the reading I've been doing. Call Rainbird and they said they are busy try calling another time.

So, per the Rainbird chart, a full circle 360 degree rotor at 35 psi gives a radius of 16 feet and 1.73 psi. If I use the radius reduction (I know to try not to) the gpm stays at 1.73. Am I correct?

EDIT: I found a picture of the Toro Multistream - for a full circle 360 degree, Label has 35 psi - 19 feet radius and 2.35 gpm. So am I correct that I should be able to space them 19 feet apart expect 2.35 gpm useage?

Try to stick with MP Rotators for now, even if you pay more

Will Hunter rotors and valves work with a Toro controller?

I'd like to stick with one model of controller.

I've decided on (2)or (3) MP2000 and (6) MP3000 MP rotators.

PGV 101 MB valves with flow control

Pros 04 PRS40-CV 4" spray bodies and PRS30-CV 4" spray bodies

Brass PVB

From my 3/4" copper water supply I'll tap in 1" PVC after meter. 1" PE to all heads.

Toro controller if it will work with Hunter valves.

I'll install 180 degree rotors at top of slope. If I end up with any dry spots, I'll add what I need to add.

Thanks for the help
