I've just compared the air nozzles from 100 series and HP+ series and can say they look different. I think it would be great to take a picture of them both.
I'll do it, if the camera catches both nozzles at one picture done in macro mode. So it wouldn't be only my words.
My opinion that the better air nozzle and paint nozzle are done and centered, the better result we can get in AB spraying. That's why Eclipse and HP+ series are different at work. HP series nozzles are much better centered and the space between air and paint nozzles is much smaller. So I think changing the nozzles between two brands airbrushes will give different results at spraying.
I think it's nozzles that most important at spraying.
I don't care much about trigger action, as from today I've got all my iwatas with soft springs from Foxy. So I'm satisfied with the trigger action. It's the spray action what I'm interested in
What I'm interested about 100SB is how fine the spray pattern of it is and what line for fine detail I could get from the AB. Iwata SB+ does well, but I can't feel calm if 100SB is better
Seriously, I just want to use the best ABs of the series. If it's 100SB among HP series, let it be. But I can't choose one until I try it myself, it seems. I also want to know what people would say about comparison of 100SB to CM-SB and iwata HP-SB+.
