aeroponic cloner spray nozzle question

what spray nozzle would you recommend for this set up? I've looked them up online and there seems to be many choices, what has been your real world experience with them? the pump is 175 gpm, 1/4" outlet bushed up to 1/2", 14 gallon tote, planning on ~50 clones
 
ended up with these 360* spray nozzles from my local hydro shop, I'll have a total of 10, 2 on each cross bar. I'll have a total of 40 neoprene collars for clones
