I've been a mostly-Simpsons guy for a while, and I've been thinking of branching out post-holidays -- in particular, I was thinking of a Shavemac. I'd rather like to try the D01, but I'm not quite decided about whether to try two- or three-band D01 first. I've been a little concerned that the 3-band would be too soft or not enough backbone, but I've been reading some posts lately that make me worry that the 2-band is a scritch monster. I pretty much exclusively face-lather. How scritchy is the 2-band compared to, say, Simpson's Best or TGN Finest? What loft should I get on a 21-22mm brush?
