Ditto on the "whatever is comfortable" thought...
BUT for what it is worth, I have a Specialized Ruby Expert...and upgrade from a Trek 1500 and I LOVE it. The upgraded components and carbon frame really make a difference and was worth the 2750.00 price tag (and that was slightly discounted). I ride regularly and pretty aggressively although I am in no way an expert or really anything other than enthusiastic. So, I can vouch for it being a well built, nice bike, but I think it is a matter of individual preference and body type.
BTW, I will post the results and "review" of my tryout of the brooks saddle!
