I started with shimano pedals - used them for several years and then went to Look Keo's.....I have used the Look's for 2 years and they are on their way out - they don't "right" themselves and I am always having to flip the pedal around to clip in....normally not a problem unless I am racing - which I do.

I will be putting the speedplay frogs on in a week or so - I have yet to talk to anyone who didn't like them....unlike the shimano and keo's I have used in the past.....
