I'm in need of some clarification here, gents. I've seen the knot size of the famed Duke 3 listed as both 23mm and 25mm on various vendor sites. I understand that there is variation within the models, but for those of you who own Duke 3's, would you say it's closer to 23 or 25mm? I'm starting to mull over my next brush purchase and the Duke 3 is definitely in the running, but I feel that a 25mm knot would allay my SBAD more effectively. Thanks.
