I was typing a reply, then Robert's reply popped up. He said everything I was going to say, so I won't repeat it.
I do like the MP rotators. I really like the HE-VANs now days more than any other adjustable. Their precipitation rate from the nozzle to the end of the spray pattern is the best I've seen. I actually did a catch cup test with multiple brands of adjustable nozzles. The HE-VANs beat them all in coverage.
When I replace nozzles in landscape beds now, I always use the HE-VAN.
