Mike, you use float on the track? That may be part of your problem. Also, I believe the track is the same price as zero stainless, but I would go cromo cause I don't care about look/weight.
recneps, does the keo have adjustable float on the cleat? Also, have you heard anything about the release tension changing at all? My coach told me spds are bad cause they don't have a C clip or something that keeps it the same, and they have a bad spring design or something. I need the float to be adjustable so I don't have to swap cleats when I swap pedals from bike to bike.
