I like the fine trigger control that the CS linear long stroke gives me. The Patriot trigger is much more sensitive and releases paint very quickly. For user with limited airbrush skill like me, the Iwata is much easier to use.
Let us know how you compare the two.
I've always equated trigger feel and action with car transmissions and engines.
Harder & Steenbeck is super-precise, but there's a lightness that makes it a bit hard to "sense" where the needle's at. Even the Infinity, with it's adjustable trigger resistance, feels lighter than other brushes.
Badger has a rougher, stouter trigger feel that's always reminded me of a truck or utility vehicle. I actually quite liked it, just had problems getting my head around the needle design and all-or-nothing paint delivery.
Iwata feels to me like a balance between the two. Not as smooth and precise as H&S, but smoother and lighter than Badger.
