I've not been on 23's in a while, but I like riding 25's on a couple of my bikes. I no longer max out the psi, around 15% under, or so. I enjoy the feeling of the skinny tires occasionally, feels like what a fast road bike was supposed to feel like for so long, fast and agile. and comfortable on good pavement. I believe one does get a sense of more feedback from the road surface. I do not want ride skinnies all the time, but I like it for a change of pace.
