Replying to Few questions about bindings - inserts,etc.

So after testing inserts (pullout strenght, etc) I'm more and more and more into binding inserts like QuiverKillers or BindingFreedom. My question is - has anyone used inserts in park skis ? Does it work ? I think I'm getting new skis next year(if I sell my current which are too stiff as for me) and wanted to inserts in them - having just one pair of bindings sounds great. And second question - more reliable are Peak15s or Jesters ? Main problem is DIN - due to my injuries I have DIN in toe piece "cranked up" to 6/7 (heel piece - 9/10)and I wonder if there's point in using binding with DIN range 6-16. Or maybe I should just leave my Peak12? They're a little worn but maybe they'll last one more season (they'll be used on two pairs of skis probably) Hope somebody can help
