Chris is right on the recent quality control issues for Simpson - this is one reason I didn't buy a new Chubby Super.

However, these issues are kind of recent - so if you trade for an older brush, you are unlikely to get them. The particular Major I refer to comes from one of the brush experts slcsteve, so it's supposedly before the QC lapses. On the other hand - don't think I am pushing it as I didn't like the looks too much myself

FWIW - I haven't had a Shavemac, a Savile Row, or a Simpson. Rooneys are great, style 1 are firmer than the rest.

Shavemacs are reportedly quite luxurious though, with soft tips - seemed to me that you want something a bit less so? Just from reading, you might be happiest with Simpson Chubby Super of Rooney Finest small style 1 ($200) - dense knots and short loft. Oh, and Plisson something

It's really nice to be able to choose a brush in person when buying...

Good luck
Ivo
