I am fine if that's just what you prefer but don't try to tell me that it's faster. The difference in traction should be obvious as well as the difference in comfort. How about CX racers? 33mm tires, most of the guys are always under 25psi at the rear. If it was that slow they wouldn't do it, would they. They benefit from an increase in traction as well. It's exactly the same with skateboard wheels...a 100 durometer park/street wheel won't roll anywhere near as well as a 70-80 cruiser wheel.
