I just switch to A23 wheels, Velocity Comp with 23mm tires, GP 4000, a much better ride than the old setup of 19mm rim with a 23mm tire. I'm 6' and 185lbs. This wheel set lets me run lower tire pressure without pinch flats. They claim the ride is close to a tubular, which I have ridden in the past. They aren't as nice a tubular feel, but close.
