Question regarding the trim nozzle: Have you tried the "yellow" trim nozzle?
Our T3000's came with the "red" nozzle, but we switched to the yellow nozzle. It puts out a little less volume, but the spray pattern is not as "course" as the red nozzle. It's actually the same spray as the "full Spray" nozzle. So we like the yellow one better. Might be something to check out. We bought the yellow nozzles from http://www.sprayers.com
