the kool stop pads are $10 a pair at my LBS. As soon as I have the money I am gonna pick some up. The guy at he shop said they will wear just as fast as regular brake pads, but I think he only said that to convince me to order extra. he recommended I order 3 pairs at a time, lol. I just hope they work good. Once I install my predator, I am gonna install a rear rim brake and also put cool stop pads on that. I wont need my clutch lever to clutch on the predator since I am using an automatic clutch, so I am going to use my clutch lever to turn my rear brake into a "parking brake" lol. that will give me 3 braes: coaster, front rim, and rear rim. I just can not afford a disc brake or drum hub right now.
