Very interesting...I can see how it would be time consuming to change nozzles in every gear driven sprinkler, but i can also see its very much worth it if you can save water from not overwatering your corners (or even your pressure from well installations as myself). I will go ahead and try these nozzles and report back on this thread in a few weeks or so, i yet to turn my system fully on, it has been raining ALOT these past few weeks here in Burley, Idaho.
Last year i converted a few of my zones from Impact (Maxi Paw) to Gear driven (Rainbird 5000 plus), i was so satisfied with the performance, this year i switched the remaining 17 out. I did a major reconfiguration on my system, by lowering heads per zone. I have a well and it puts out 13 GPM at 48 PSI. Bought a Hunter pro C, 7 Irritrol 2400T valves, Added pre-built Manfolds, RB funny pipe and fittings, ran all new wires, you name it. I ran into this site last year, and mustard enough courage and Back strength to do it myself. All you guys have been really helpful, Thanks a bunch, saved myself a few thousands.
