As only a couple of people seem to understand....sometimes buying a binding like the P18 is not about having a DIN range that high, it's about the material in the binding itself.
Bindings with DINs to 10, 12, and even 14 are often made with a lot of plastic in them, thus making them less durable and more prone to breakage under extreme use. A binding such as the P18, or old Solly S916s are basically pure metal, and thusly, just about bomb-proof. I know I blew up a couple pairs of Markers and s912tis simply because those bindings are designed for more tame, recreational use where a lighter binding is more advantageous.
It's not all about the DIN range people.
