I was about to go to Speedplay, for fast clip-ins racing crit's, but when I started only using my Look KEO Carbons, rather than going back and forth between them and some SPD's when I switched bikes (only have one bike right now), my clip-in issues went away. Consistent use gave me the muscle memory I needed to get the clip-in working right, and I walk on crushed granite every day getting to the garage, which from what I hear would be a problem with the Speedplays.
