CADs and COs (I've owned both) are both a little too stiff for the SL in my opinion. They're more suited for stiffer, big mountain/powder setups. I rock a pair of Rome Targas on mine and love it. I ride my SL all-mountain freestyle. Any mid flex binding would be a good match, like Ride Deltas or Alphas, Flux Feedback, or even a set of Rome 390s if you like a little more flexible binding.
