The Centurion is not an '87. It's not even '83 or '84, when the silky smooth Lemans RS had really nice components (unless someone swapped those in--it looks like the group from an early 80's Raleigh Rapide combined with Suntour piggyback shifters, and not the ratcheting LePree's from the 83/84 era).

At first glance, I saw the shifters on the Centurion and was prepared to defend and advocate for it. However, it appears older and more dated than the Bianchi, so I'd recommend, for your needs, the Bianchi, if it fits. If the Centurion truly was an '83 or '84 that someone cannibalized the parts from, it's a lot smoother frame, but is 27" on the wheel size, so I'd probably pass unless I wanted a project.

Sorry to disappoint all those who figured I'd go for the Centurion, but in this case, for his needs, I'd go with the Bianchi. I do agree with the Captain, the Centurion has more soul, but it'd be a project to bring it to the fore.
