dont know why he posted but what he says is true, yes they have a little more metal in the heal so they are the next step up from the garbage that is the Z12 but they really arn't a legit 14 din bindings. the spring may give you a high din but your going to tear them off the ski so if you like one use only bindings these are for you.
Sell em for 180 and be happy man. Or try ebay but he is right they are not going to sell for over 200 on here. plus you can get them for 20 more at retailers and that allows you to choose your color and brake width.
