I've been shaving with the R41 since I got it. I am finally coming around to it's way of thinking... I have also used the Gillette I got from BeJay. Thank you brother for the hookup. That razor is wonderful. If I hadn't spend a ton of money on the R41, I would most likely be completely happy with the old school Gillette. Two passes with the Gillette is better than one with the R41, but as of now my face can only handle one with the R41. So for speed and efficiency of the whole operation, the R41 is my way to go. If I have time and I want to get all the way to BBS, I will use the Gillete. The R41 may be double chin friendly, but you'll probably need to get your chin way up to stretch things out...
