Thanks to both of you for the tips - and I was already considering geometry and wheels, etc., but had not thought about the fork rake. My fitter is recommending that I talk with Richard Schwinn directly about what I want/need to help me settle on the most appropriate frame - and my fitter will speak with him as well after our session. We are fortunate in that Richard has a daughter in the area and he has a personal relationship with my LBS.

I am taking my time this time as I would like this to be the last road-type bike that I buy barring having to replace one of my bikes for some reason.
