Always interested in what "sloppy" means. Will the fraction of a mm of play in any tracked binding make a significant difference in how quickly your force is changed from one edge to another? Or is this a psychological issue? Does noticing a difference between two bindings translate to actual mechanical differences that affect skiing? My hunch is our own lame reflexes and sketchy muscles are gonna be a vastly bigger variable than binding play or materials, unless we're a world cup racer. Or beat on our bindings with a hammer for relaxation. YMMV.
In any case, agree that the 14's seem to produce slightly less "slop" than the 12's. Whatever that means. (Actually what it may mean is that the 12's are significantly lighter. Something to consider if you hike for turns.)
