Replying to Should I turn down my bindings for park skiing? If so how much?

Its spring and around this time of year I always get it in my head that i am going to go learn to throw down in the park. So my question is right now I am running my bindings at 12 toe 13 heal on my normal freeskiing skis and am worried that my 175 lbs self will not be able to put enough forces on the binding while skiing park to release in a fall so I am thinking of running the bindings on my park skis lower. Is this a good idea? How much lower should I be looking at?
