I have a Parker black badger brush. I also have a brush I rehabilitated and put in a black badger knot from "The Golden Nib" The Golden Nib is slightly stiffer and a little more exfoliating than the Parker, so I understand 2 different suppliers can have the same product description with 2 different products. That being said... I was able to get another brush to rehab that has a matching handle to one I already own. I want to really put a high end knot in it. I noticed that there are 2 different silver tip badger knots on The Golden Nib (Silver tip standard, and Silver tip premium) and a "high mountain white" can anyone compare and contrast characteristics of these for me and give me a "what to expect" because their product descriptions are quite lacking.
