I'm thinking about finally going for it and getting my first silvertip badger. I think I'm pretty settled on Shavemac because I like their customizable options and reputation. I'm just not sure exactly what to go for. I know I want a bulb knot because I've never had that style. I face lather exclusively. Right now, my absolute favorite brush is the Semogue 620 boar due to the great backbone and scrubbing. I would like for my silvertip to have similar backbone, but with the luxury and soft tips of the silvertip. I'm trying to decide between the D01 or the regular silvertip. Any recommendations?
