I'm looking to purchase my first Simpson's and I have narrowed my choices down to the Berkeley 46 and Commodore X1. My question for all of you is what the differences are in the two brushes. Both the Berkeley and Commodore share a knot size of 20mm and loft sizes of 45mm and 44mm respectively. Handle lengths are 45mm for the Berkeley and 46mm for the Commodore. West Coast Shaving has the Berkeley priced at $49 and the Commodore at $50. According to everything I can see, the two brushes are basically the same, with the only difference being in the shape of the handle. Is there anyone that has used both brushes that can comment on any differences? Is one brush more or less dense than the other? Does one brush show a greater bloom after use? Any help will be greatly appreciated.
