I just received my new Feather AC SR folding shavette. This razor is between the SS and DX. It leans more toward the DX but has a fine lip that makes it more forgiving but not as round as the SS. The weight of the SR is almost identical to the DX which I prefer. I find I don't have problems finding the right angle like I do with the SS. Just lay it flat and away you go. Going to put my SS's up for sale, I found the perfect shavette. I shaved with a Feather Pro and Kai mild blade and got a very smooth, irritation free result both times. My beard is heavy and the extra weight made it very easy to get a close shave.
