Just had my first shave with an R41. I think the question of this thread should be "Muhle R41...can anything beat it's efficiency without being aggressive?" It was so easy and comfortable to use. I now understand why it has such a following.
BINGO!
Such key words indeed. I also think there is an ocean of difference between efficient and aggressive.
I don't consider the R41 head to be in any way aggressive. I do consider it to be highly efficient.
