Been riding Micheiln Pro3 Service Course 23's for a year now, had Continental GP4000 23's before. I like both very well and the roads where I live are crappy at best save a few miles that were resurfaced last year. I doubt I could feel the difference between a 23 and a 25 it is so minute. My wife's Trek has 700X35 on it and it feels like riding in a 60's American land yacht, to me, she loves it though.
