I have both the 520 and the Volpe, and plan to keep them. Love them both. They'd be waaaay too small for you anyway. I use the 520 in the USA, and the Volpe is currently in storage in Europe awaiting my return in May.
The reason I posted is just to offer a note about the Volpe. Bianchi has made some changes to the design of the bike. Unless I'm mistaken, The newer models do not have the low rider mounts on the fork nor the water bottle cage mounts beneath the down tube. If you're interested in using it for touring, make sure it's one of the older versions which have these handy little features.
