I picked up a new Fuji CCR3 about two months ago as an motivator to start riding again. The bike is great, sure beats the 1991 Schwinn 564 that I had sitting around. I didn't like the seat and tried three others, none of them fit me well.
I stopped at another bike shop today and they had a Bontrager Saddle Sizer. I sat on it to make an imprint, I then matched the color formed by the imprint to the color on available seats. Seleceted a seat, installed it this evening and went for a ride. Wow, the best so far. Granted I only rode 10 miles but so far so good.
If you are having problems finding a seat that works for you give the Bontrager Saddle Sizer a try.
