i ride the SPD-SL pedals (look style, lance pedal, etc) by shimano. i have them set to their bare minimum tension, and i have never pulled out of them, and i can give the pedals a good yank on a stand-up-and-sprint. i ride them on both the track bike and road bike, and i would recommend them to anyone. only thing is the cleat is not designed at all for walking as it is sizable.
