I also have Ritchey Speedmax tires (700x32) that came on my new bike. The rolling resistance feels surprisingly low, and they smooth out the bumps well. I would agree with others that they don't corner as well on pavement as a smooth tire would. That's not a big issue for me, and I plan to run them at least until winter is over before putting on some 700x25 smooth tires that I already own. We'll see how that goes....
