Decisions decisions. I finally decided to try a brooks. Now I can't decide which one. The woman's b17 was my first choice, then I saw the sprung version. This is for my Bianchi that I will tour on (yes girls, long slow and happy!!!). The sprung saddles are supposed to be most comfy for touring, but gosh they look humungus! Do the springs make that big a difference? Any opinions out there?
