LemondZurich, great looking bike and just what I have my eye one!

I had more or less settled on a 58cm Specialized Roubaix until I saw the Le Champ Ti recently. On their website BD present the carbon Le Champ as a semi-relaxed geometry and compare it to the Specialized Roubaix. I'm getting a little longer in the tooth (47) with some upper back and neck issues, so comfort has a priority over an aggressive race orientated geometry/fit. Do you find the Le Champ Ti fits that description. Or even better have your ridden a recent Roubaix and can you make a direct comparison?

Thanks for any help you can provide.
Kevin
