Right now, with the long commute, I'm thinking a fast tire and all my wheels are tubies right now. I've had no issues at all yet, just thinking long term. Thanks again, great info.
Vittoria CG and FMB Paris Roubaix are 700x27
I doubt you'll find many (any?) here commuting on tubulars, so you're blazing your own trail.
As far as cyclocross bikes, that's become a fairly vague term. Historically, it meant high bottom brackets, but that's changed a lot. Some still are, but many are very similar to road geometry now. Their geometry tends to vary more between brands than road bikes.
Having a variety of bikes, I would recommend a "sport tourer" if you want something different, and only then if you want a) wider tires than you can run on the Madone b) an easier way to carry a rack c) better fender accommodations. I have cyclocross bikes, but the only thing they offer over my Salsa Casseroll (fenders, rack, 700x28) or Speedvagen/Giant TCR (700x23or25) is the ability to run even larger tires. Unless you're running studded tires in the snow, I don't see the point for you.
