The only people at the track who regularly use anything but looks, spd-sl, or speedplay are sprinters. They have thighs approximately the size of your mom and do things like rip teeth off of cogs.
Thor Hushvod rides Looks and he is one of the best sprinter on the road. He is stronger than anyone on this forum and if he pulls out of the pedal its because either he did something wrong or the pedal is defective.
