If I can ever get caught up from my spending on vintage Gillettes, I am going to try out the Semogue brushes. I haven't heard a complaint about them yet.
Right now I am using VDH badger, a VDH boar that came with the luxury shaving set, and a Tweezerman badger. I haven't had anything but good results with those and they will "do" for now. They all shed a hair or two at the beginning but all three have settled down to be good brushes.
Before the end of the year I'll get a Semogue or two. I'm stocked up on razors, creams, soaps and other product.
And I could always use more Feather blades.
