I've always wondered why there are (usually) 2 sets of cleat mounting inserts on shoes. Which one are you "supposed" to use, and what is the bennefit/detriment to using the forward mounts vs. the rear ones (and vice-versa). I've always mounted the cleats to the back mounts. Could I be missing something?

Personal preference as far as I can tell.

Foot position-pedal-cleat combo. Ideally you want the ball of your foot just in front of the axel, hence the cleat should be just behind the ball of your foot. The 2 positions and the ability to slide the mount allows you to adjust placement.
