I have many nice brushes but most are brushes I have assembled aside from a few from Arno, Zenith, and Semogue. Always wanted to try a Simpson. After finding a vintage brush in a junk shop and using it a few times. I broke down and ordered the KH3 (Insane Amazon price). My favorite knot size has been 26mm. I have a few 24mm knots and a couple 28mm but the sweet spot is 26mm. After using the smaller KH3 a few times I am really beginning to like it. Wish the loft was a little shorter but it is overall a very nice brush. I only wish I would have picked up a Thater before they were all gone. Since I'm a brush junky I imagine another Simpson or two will end up in the collection.
