I have CR18 rims (from Harris) with Kool Stops on my new bike. They stop perfectly dry, decent wet (I have been riding only fixed for the last 8 years, so I can't compare). I had my wheel built around a new SA 5-speed hub, which has a LOT more range, and I love it (wanted Nexus but only the SA5 had 110 spacing). Might have been cool to try the drum brake but I got a good deal on the brakeless hub.
