RazoRock BC Silvertip Plissoft synthetic brush. This thing is excellent. Soft and whipped up a ton of lather!
In the spirit of this thread I can now report that as of this morning I started using the Fatip Piccolo SE OC too.Fatip Special Edition Piccolo Gentile and Proraso boar brush. Need to get used to this razor, but very efficient and my cheeks are insanely smooth at the moment.
