Can you ask the pro bike fitter before you make an appointment if she will fit you, offer saddle recommendations at the fitting (once she sees your body/position, etc), then tweak your fit later on? I've never had a pro fitting, so I don't know how it works. I would hope they would let you come back for a final adjustment if anything isn't 100% right on.

I ride An Atomicas, and am really happy with them, but I don't ride long distances. I've had the older one for almost 2 years, and ridden year round with it, and it shows very littler wear. I know some people have had trouble with stretching, but I haven't.
