I have used Spedplay Light Action, Speedplay Zeros, Dura Ace Shimano SPD-SL, Look and have tried SPDs once. They all have their purposes. My favorites are the Speedplay Zeros. The SPD-SL didn't work for me, but I was new to cycling when I used so maybe I didn't give them enough time. I used them for about a month and had a hard time clipping in and out. I used the Light Action for six years and then gave them to my wife when I bought my Zeros. I use the Looks for my spin class which isn't a fair comparison.

What issue are you having with your pedals?
