Anyone have any experience designing/installing/maintaining any of the following? Would appreciate any/all experiences good/bad. Hunter Micro-Spray nozzle (for spray pop-up bodies). Hunter Multi-Stream nozzle (for spray pop-up bodies). Hunter PCN Bubbler nozzle; specifically looking at whether the nozzle is one piece or two-piece like the Toro 570 bubbler nozzle where it's easy to knock off the top piece. Rainbird Xeri-Pop Micro Spray pop-ups (for 1/4" drip tubing).
