Da Vinci doesn't get a lot of press, but the silvertip is some excellent stuff. Easily up there with Shavemac, Thater, VP Leonhardy, and several other German brands. There's only one of these for sale for this model, but it's a 25mm knot and only $48.81. As long as you are okay with a slightly longer loft and bigger knot you couldn't ask for a better deal. Density does not suffer on the brush either. You'll find this for sale on Amazon.
