Follow-up report: First, I received an inquiry about the knot size. Simpson specs this as a 23X50 but measured with a quality digital caliper mine is 25X50. I'll be interested to see how Rick's (Bavado13) measures. As Jarrod at Superior Shave has documented, there can be some material differences in size between the same Simpson model. The slightly larger diameter may contribute to the reduced density if the amount of hair in a knot is determined by weight (I have no good reason to make this wild-a-s speculation). So I face lathered using MdC which is not the greatest test of any brush's ability to build a lather as the worst floppy mop of a brush can make a lather with MdC. However I was really testing how it felt on my face building the lather. It's not really fair to compare it to my Chubby 3-band super but I will anyway. Completely different feel, I wouldn't be surprised to find that the Chubby had 2X the hair per square mm. This allows the Duke to give up lather much more easily, which is critically important in a face lather. Being a 2-band compensates for some, but not all, of the loss of backbone and I'd say this Duke has plenty for me but guys looking for a bit of scrub would be disappointed. I'm hyper-sensitive to scritch (hate it) and had all the nerve endings on alert to see if they could detect any. I'd say very, very slight and only when I was trying to provoke an adverse outcome by using a really heavy hand. So even for the scritch-phobic like me, this brush feels great on my face. I wish I still had my Duke3 band in Best to compare it to as this brush is more than twice as expensive. That said, I'm happy to own it.
