Well, I would go to your local ski shop and ask for their help on that.
Plus, it depends on what you do (somewhat) different bindings have different max DIN.
Higher the DIN, the harder it is for the ski to pop out on accidents.
Go to your local ski shop, and tell them what kind of stuff you ski and stuff, and they match you up with bindings that hold for your specifics.
Some bindings have a lower max DIN for this type of skiing and some bindings have a higher max DIN for THIS type of skiing.
This is all my opinion.
This is what I did when I got my skis.
Hope this helped.
