I have been lurking around this site for some time and have gained invaluable experience from reading all your posts. I figured it was only right to register and contribute when I can. My first question for you all of you is this: Does anyone have any experience with Nelson's rotating spray nozzles? I have a pretty severe slope on a new install with sandy soil and have been told these multi-stream rotating sprays are the easiest way to go compared to bubblers or drip lines. Wind may be a factor as well. They look like the ol' Toro 300's to me but cost much less when fitted on an RB 1800 spray body.
