Well, rode about 10 miles with the clipless pedals and I gotta say theres really no reason why you shouldnt be clipless. Not only are you able to use more muscle but your feet stay put on the pedals and its alot easier to pull your bike up over obsticles. As for the injury report, no accidents but coming up a climb I hit the wrong line, my front tire hit a larger root which cause me to stop and I couldnt get my foot out in time. Down I went.
