The Tricross Sport and Comp have the same frame geometry specs in each size. The Sport is more what you're looking for. The price is right. The Comp is sweet, but even I have a hard time justifying the premium for the '07 model.
I like the 32c tires. It's changed my mind about skinnies (23c). They are indeed too skinny! Thinking about even wider tires (35-38c) for winter and sloppier rides.
Remember, the only perfect bike is the one makes you want to ride a lot!
