i love my jet 90 for clear with the right setup sw spot clear is 3-1-10% there super glamour is 4-1-1. I spray metallics with one of my 3 nr 2000s i spray solids with a sata rp and i also have an anest iwata that i use for solids i learned how to paint with a nr 95 with a 1.5 and a siphon fed but that was when we used mostly acrylic enamel or synthec enamel .
i tried cuting my flow back with a 1.4 but it didnt work its tricky to paint when it 100 degrees in a down draft and your boss is breathin down your throat to get that car out and doesnt want to hear any thing about flash time
