Everyone has their own preference. I personally do not like going over 4 flow. On a6 wand I would go with 8015. I get my jets from other sources outside the industry because amen I use multiple jets in a wand I like a more narrow pattern. This industry does not supply the 65 fan pattern I like. The reason I use 65 fan pattern is because it has less overlap and for me that means less streaking and a more even pattern. One of my old suppliers told me I'm too picky and i prefer certain things that nobody else in the industry asks for.I have a 6 jet wand and was just curious what size jets work best.
That's why I like the 65 less likely that happens.@Ara Klujian Teejet produces jets with the suffix E... i.e. 6501E that means "even spray". Farm suppliers carry these in stock for boom sprayers where every penny counts for distribution. Worth looking into if you want even impact. I offset my jets spray patterns just enough that only 2 fans touch, if they run into each other it creates kind of a dead spot.
