Thank you all for your reponses.
I went down to our LBS that sells Jamis today and rode a 53cm Satellite (which I don't want, fit not bad but not very reponsive) and then he only has one other road bike to try; a 55cm Quest. It is too big for me, but after riding it I know that I'm really interested in the Quest model. Just can't ride the size I want... So I don't know for sure if a 53 or 53WSD or a 50 could be the one?
Going to drive 100 miles tomorrow to another town to try out some other bikes. A few friends/road bikers have highly recommended one shop there that carries Bianchi so I'll go see what that's about.
Thanks again, I'll let you know how it goes.
