So today was my first (half) shave with the Muhle R41. I lathered up (TOBS Avocado) and shaved half of my face with my custom merkur 38c and the other half with the Muhle. Two passes, WTG and ATG and the Muhle left me with a beautiful BBS shave while the Merkur left me with a DFS. Tomorrow I will switch and see if the results are similar. I am more than impressed with the Muhle.
On a side note what would be my best option if I wanted the R41 to have a longer handle. An extra 3/4 of an inch or so would be great and I remember reading that Muhle heads are interchangeable. I think I may have gotten used to using my Merkur (about 4 oz. with a wide malachite handle).
