I have been using a Selle San Marco Roll saddle for the past year and a half. I bought it based on many of the reviews indicating howcomfortable the Rolls was. However I only find it moderately comfortable After about an hour, it starts to wear on me. So I'm thinking of getting a Brooks B17 again based on many of the reviews I've read on what a comfortable sadd;e the Brooks is (eventually after wearing it in!) So I'm looking fow any feedback on those who have used both a Rolls and a Brooks. Did you notice a noticable difference?
