I made that statement yesterday and Henry said really it blew him away. I noticed our junk nozzle pile was showing lots of brass nozzles. I'm pretty much replacing all the 20 spacing brass nozzles I've installed over the years with MPs. I haven't made a trip to my favorite little Irrigation store to stock up on brass nozzles in ages. The MP has killed the brass nozzle in my inventory. Except for 3', 5', 10, brass peanut nozzles I'm not going to stock them anymore. The new RB nozzle XPCN? may eliminate those brass nozzles as well. This is after 28 years of satisfied use. Times have changed. With the cost of copper and all the theft of copper risers we've been forced to quit using them as well. AULD LANG SYNE to a great product.
