I think Patrick's comments are right on. I rode a metric century today on Paris-Motos (mounted on 32 spoke Dyads laced to Phil cassette hubs). They felt fine cruising along solo, but I sure didn't feel like trying to wind them up to jump on one of the pacelines that passed me. Had I been on my crabon go-fast running on 24/27 spoke Campy wheels and 25 mm (measured 26 mm) Vittoria Open CX's I would have been more able to make the jump. What wears you out in a fast group isn't so much rolling resistance as the constant accelerations and decelerations, and light, skinny wheels and tires seem to spin up faster.
That said, I was very comfortable today with 65 PSI in the tires and a sprung Brooks Champion Flyer under my butt and that was what I wanted for today's ride. 65 miles and 1655 feet of climbing in 4:32 won't get me a pro team contract but it felt fine for this overweight 52 year old.
