Hammerheads are an extremely versatile and responsive binding. I've skied it on 80mm park skis to powering my big 130mm pow skis. With the different positions you can adjust how "stiff" the binding is and how active the flex point it. It is extremely bomb proof and I've never had any problems with it. If your looking into touring then I would suggest springing for the Axl. The tour mode is legit and the binding is way sturdier than say a BD O1. I ski everything from park to big lines on my Axl and it's never failed me.
