I generally only do factory brushes though I have done a few customs because of the handles. I ended up selling all but one because the tips on the customs were too soft and I want scritch. The one I kept I'm thinking of sending to Bern (Shavemac) for a 48x23 with scritchy tips. If anything is like Forrest Gump's box of chocolates, it is shaving brushes. :shrug:
