I was looking up precipitation rates for mp rotators and rainbird 5000s the other day while programming a RB smart clock and it seems like they can be matched exactly.

It seems the sentiment here is using rotors and mp rotators on the same zone is a last resort. Why?

that's a huge plus for RB if the facts are there..

I'd cross a picket line in a heartbeat.

Rainbird 5000 rotor performance chart.

Its kind of hard for me to believe an mp can put out the same amount of water as rb 5000 with a #4 nozzle, but that is what the chart says.

It can be done if all the heads were not installed with the biggest orifice on the nozzle tree. I hate when that is done. No, the 90s, 180s and 360s are not installed on separate valves either. If that were the case, I would not be betching.

i put at least one or 2 mp's on each job to catch any odd shape perimeters of the turf on the rotor zone.
at .7gpm for a 180 mp2000 and the same precip rate.
they work great for that stuff.
