Addition: The deciding factor was my own obsession. I've spent a long time researching a new bike. I bought a starter bike last July figuring to upgrade in a year if I really got back into cycling. I started researching a new bike in January, and by March I had decided on the Roubaix Pro. Later, I decided on the Comp. The proverbial straw was the thought of buying the Comp, and always remembering that I had originally picked the Pro and settled down a level. The Pro is more expensive now, but I would have likely spent more on upgrades after I bought it once the obsessiveness kicked in.
