I had a set of Boyd carbon hoops back in the day. Stopping power was good enough in the dry to ride around the city and do twisty mountain descents on narrow roads. Brake pads made a lot of difference. Being black, they heated up in the sun which obviously isn't a problem in Seattle but it required more judicious braking then I was used to on some of those long twisty descents when I'd take the bike to the other side of the Cascades.
