Thanks for the input, everyone. Much appreciated. I do like my Shimano pedals and shoes. I was just wondering if the grass was greener. But, I am in a position of "if it ain't broke..." It seems like everyone has a favorite and I am curious what Time claims their unique value proposition is versus Speedplay versus Crank Brothers, etc. Again, this is most likely just an academic exercise for me. I should remain loyal to Shimano since in three years using them (since going clipless) I haven't fallen or had any problems. (He says knocking on wood.) but, it is like the guy who has only eaten one type of candy and then discovers the millions of other candy available.
