While I'm riding another version of Speedplay -- Light Action -- (my stoker/wife elected to stay w/ her Look pedals), I've been thoroughly satisfied with them. Lighter weight & slightly more ground clearance. The only thing that I'd add is that clipping in requires an even/slightly down heel action (more like stepping ON the pedal) vice the toe-in-the-Look pedal AND then press your heel down. Durability's been great, even w/o cleat covers.
