I went through your dilemma last year, although I don't do racing. I wanted a light bike that I use mainly for fun rides but which can double as a light touring bike. The only one I could find in Vancouver that fit the bill was a Marinoni Sportif made in Quebec. I am completely happy with my choice. It is an extremely light steel frame, with an amazing flex that makes for comfortable long rides and has the mountings for a rack that can handle panniers.
