I agree with the others who suggested the Expert ... I knew that I wanted the Ruby, but couldn't justify the extra cost for the Pro since I don't get to ride nearly as much as I'd like. So, the Expert seemed like a good compromise. I also rode the Comp before comitting to the Expert, but I don't really remember how different I thought they were at the time. It's definitely an upgrade from my entry-level Allez and with the type and frequency of riding I am able to do, I don't feel as though I'll "outgrow" it anytime in the near future. i've been extremely happy with it.
