There's also old boys that ride the track on Keywin pedals, I think there's two types, the ones that float on the axle and ones you lock yourself into with a lever underneath? The later may not be Keywin and may or may not have pedal float.
There's also a few that try and ride different variations of standard spds but generally we try and discourage that.
The later, or latter, sound like Cinelli M71, otherwise known as the pedals of death. A pin locates in the shoe plate and they're fine for tt or pursuit but really don't let your feet go when things get crashy.
