Most guys who use Iwata brushes really like them. To me, the right brush is determined by the tip size you need. Iwatas can be had in truly tiny tip sizes but which size do you need? A .2 mm tip HP can paint very fine lines if your skill and control is up to the task and if you are shooting properly thinned paint. But it isn’t ideal for thicker pearls and flakes. Maybe you can use your Badger 150 for that and a small tip Iwata for finer work. If you want to stick with one brush for everything, an Iwata Revolution BR (.3 mm) or Eclipse (.35 mm) will do it all. One thing you will notice: the smaller the tip size, the more expensive the airbrush and the more costly the repair parts if needed. And the smaller the tip, the more exactly the brush needs to be fitted to use it, so be extra careful with those fine tipped brushes.
