OP some of the best advice you will get is from reading GIACUser's posts. BTW my original water/meth system is Devil's Own (GIACUser I only bought #4 nozzles from you not entire Snow water/meth system) and the Devil's Own system has been reliable for the aprox 5 years I've used it but the progressive adjustment knobs are not super precise and take a little getting use to but the end result is it works.
Ok now I remember who you are.
