I have a Waterford cyclocross double, which I use as a road bike. (lugged steel)

My other bike is an aluminum flat-bar triple with cyclocross geometry. I use it as my rainy-day/commuter/utility bike.

Cyclocross geometry seems to suit me well. Having my utility bike be made of aluminum keeps me from worrying about rust. (it does get... moist... around here). I feel ok leaving my utility bike locked up in front of the library or store or whatever, which I would NEVER want to do with my Waterford.
