Thanks, the Duke 3 is what I was thinking , always good to run it by youI like small knots so my favourites are the Chubby 1 but if you have large hands or you bowl lather then you may find the handle a bit small. I like the Classic 1, it fits the small Simpson travel case perfectly and is almost as dense as a Chubby. For longer handle, maybe for bowl lathering, the M7 is excellent. But, if I had to choose just one Simpson brush, then the Duke 3 wins. Whichever you buy will not disappoint as all Simpson brushes are quality products.
