What would be your choice for this distance. For example a 20' x 40' area. I'm against dogging down a rotor that sprays 30' plus. I'll knock them down a little but only a very small amount. Kind of in between land for MP 2000/3000 from my experience. Was thinking about the RB 500 MPR nozzles-red which are listed at 25'. I've never used these though. I think Leary is a fan of these, if so please chime in.
