YMMV for sure on this issue. I never liked 23c s all that much though. I used to ride 25c a lot; lately I've been riding 28c tires. I think some of it has to do with speed. If going fast, some of the weight will move off your butt and to your hands and feet; going a bit slower a wider tire is better. I don't race anymore and the 28c tires work for me now well.
