My guess is that you won't notice much difference. I have a Diverge with 700x38c tires and a Cervelo Caledonia with 700X30c tires, and ride the bikes interchangeably over paved roads. I do notice that the Caledonia accelerates more quickly and seems a bit faster up hills, but, with no scientific measurements to go on, I don't think my overall ride time is noticeably faster on the Caledonia than on the Diverge. I find them both equally enjoyable to ride on paved roads. I'm talking about two different bikes, not just different tires, and the Caledonia is lighter than the Diverge. Unless you're trying to squeeze out every last bit of speed, I'm doubtful that you'd notice much difference with thinner tires.
