Good brush: I have had one for a couple of years. The knot is a hybrid fan-bulb with Best hair, dense and scrubby. Mine is sort of like a short-lofted CH-1, which makes it better than a CH-1 for me. The only drawback is that the handle is a bit short at 40-mm. If it had a 50-mm handle I would probably use it more often.
I am quite happy with my Classic 2 and Commodore 2. The first is short, dense, and good for a face lather, and the latter is very good with a bowl, but not nearly as dense or firm.
