A good, simple Dynafit design without all the fancy stuff inherent in the radical design. I've trusted these bindings on a lot of skis and Dynafit has replaced the heel risers, so they are still going strong. If not beaten too much, the rotating heel piece will stay in position, and if it does start going both ways, you should be able to pack it with something. Few places still stock these so I'd get em if you can, though the brakes for wide skis may be tricky to source.
