+1 for the Speedplays - Any version to me is better than the others I have used. I started on SPDs on my MTB and they are great for that bike, but on my road bike I quckly got into a good Sidi Shoe and the Speedplay Light Actions and never looked back. I'm thinking about going to the Zeros. I have pulled my shoe free of the Light Actions a few times going hard up-hill and that is not where you want to pull out. Ouch!!
