I've had an assortment of boomless tips over the years, I just run a 4 gallon per minute 12 volt pump, so my options are slightly limited. I bought a Hamilton #5 boomless spray tip ($26) this week, and fashioned a bracket to hold it. By far, the best tip I've ever used. I've got it 52" off the ground, and I think I'm going to lower it some before I settle in to really using it. It sprayed both walls of my 40' shop, pretty high up the wall. I believe I'd rather spray a little narrower strip, and concentrate my volume. Well worth the money, and an improvement on the $170 tip I was using.
