I love the iKon Bulldog, it looks fantastic on the R41, and gives it the grip and heft it needs. I've got a Bull Mastiff as well, and it's a good shaver with it. If you're sensitive to the aesthetics, you might not like it as much. The Mastiff has a yellow-ish cast, and is a slight mismatch for the R41 head. It doesn't bother me, but it might you.
Of course, the Mastiff you'd need to find used, as Bob has recently passed.
