I own, and have owned, many different synthetic brushes. I tried a couple of "higher end" Simpsons synthetics (Duke and Chubby) and the Simpsons Trafalgar, but my favorites have been rather inexpensive brushes from Yaqi, PAA, Turn-N-Shave and RazoRock. While I have always wondered about the famed Muhle STF, I just figured it couldn't be worth the premium price. Eventually, of course, I just had to try one. I found a very good deal on a new 25mm STF ($58 delivered from Ireland). Six days later it arrived, and I couldn't wait to give it a try. Since I had already shaved today, this wasn't a full test. Following the instructions that came with it, I first washed it out and then created a test lather. I decided to face lather even though I wasn't going to shave again today.
This brush really lives up to its reputation. No other synthetic that I have used behaves as much like a badger brush as the Muhle STF. No lather flinging, plenty of backbone but very soft tips. Flow through is excellent. After the disappoinment with the Simpsons Platinum brushes, I have to say that I was expecting to be disappointed again. But this brush is truly in a league of its own among synthetics that I have tried. I know that there are some other new synthetic brushes that are getting rave reviews (G5's with various letters from a couple of different sources), but I think I'll be content with my Muhle 25mm STF.
