Tell him to go with the new k rain To cut distance one cuts flow.
The 5500 would be a better choice IMO than say taking a head that cover 30' and choking the chicken to 20'. King of hackish to me. I see #9 pgp's choked down to 10', I just shake my head.
Another obscure sprinkler that would absolutely positively give you a specific 22-foot radius, is the Toro Stream Rotor head with the special adjustable radius nozzle, which is the 03 nozzle equipped with an internal flow control.
I tried those years ago: crummy pattern. My choice is still 5000/5500 or even the 3500, which I've had good luck with.
I never used them because I liked the constancy of the original nozzles. Put one on a high-pop 300, in place of an 02, and got a decent pattern from it when dialed back to 20-22 feet, so maybe the extra height helps the coverage.
Im assuming ( I know , I shouldn't) that the gentleman mentioned who dosnt like to dial down is a landscaper who does mostly new construction and see's lot of washout when first installed.
I don't think many of the new nozzles would please bare-seed landscapers. That downward spray from a modern nozzle is just what they wouldn't want. Toro wrote an explanation in response to complaints about close-in coverage on their S700 nozzles, stating that the close-in water was directed upwards instead of downwards, with the intent of minimizing washouts.
