At the moment, I'm eyeing either the Harder & Steenbeck Evolution or the Badger Patriot. I'd been leaning toward the Patriot and it's purported ease-of-cleaning properties (especially the trough of the paint cup - a persistent problem area with my Iwatas), but then I read a review of the Evolution that reported great success with Vallejo Model Air, which the reviewer had always had problems shooting through his Iwata. Since I've had a similar experience, that got my attention right quick.
My main goal is to find a good general-use brush. From fine-ish lines up through medium coverage. To date, my Iwata HP-CS has been filling that role, but it's been very fickle of late, despite extensive stripping and cleaning. A second brush in the role might even give me the ability to dedicate one to true acrylics and the other to Tamiya, enamels and lacquers.
Obviously, the Badger is cheaper. But other than that, anybody have any direct experience with the two?
