If you like the high efficiency of R41, you can try the Razorock Wunderbar. Using different angles you can achieve the most exciting to the mildest effect. Slant razors are the best IMO.
...and if you're looking for a slant that isn't quite so "efficient," I suggest the ATT S1 or S2. I have the S2, one of very few all-stainless open comb slants. It's more aggressive than the S1 so I'm told. I like it so have no reason to try a milder slant...
O.H.
