So after doing lots of research and watching youtube videos, the eggbeaters and speedplays look nice. On the speedplay pedals, the light action and X5 chromoly are the same price, but the only difference I can tell is the float. The light action is 15* and the X5 is 20*, so I'm not sure how to approach this. The Shimano SPD are 6*. More float seems like it would be more comfortable and easier on the knees, but less seems like it would keep you more locked in place for consistent pedaling. Hmmm.... discuss.
