I think you made the right choice. My brother-in-law, who has a lot of back issues, loves his Roubaix, but he'd be miserable on the Tarmac. Funny, after I posted my earlier comment, I had a question on my food/fitness forum about the ruby/Amira comparison. Can't wait to see pictures. Are you getting a '12 or '13? And color? Pictures!!!!! They've, of course, changed all the graphics/colors.
