I'm planning to get a set of the Tektro CR720, and I want to install Kool Stop salmon pads. I'm not sure if I need to buy the "thinline" shoe, or if there's a "slide-in" pad I can install on the cartridge that comes with the Tektros. I'd much rather use the cartridge so I wouldn't have to readjust the brakes every time I replace the pads. Does anyone know from experience if the Dura-Ace/Ultegra Kool Stop replacement pad fits in that cartridge?
