Couldn't agree more. My Trek 520 has 32's and is very comfortable. Problem is the weight. When I get done with a long ride I am beyond tired. I don't hurt, but can barely function. My other bikes are not as comfortable, but I am nowhere near as tired, but my body hurts. Wonder if putting larger tires (already have 25's) on the faster bike would make up for the comfort issue on longer rides?
Edit: Or maybe get my lazy ass in the gym.
