The schizofrantic's only fit certain skis i belive.. like extremes and kung fujas. If you try and fit them to others the the screw retention would be terrible unelss you really do it well. Basically the ski is built with the holes ready drilled into a tiny metal base plate on the ski, thats why the new season kung fujas and extremes are set up with the schizofrantic's
K2's factory lineup comes with the schizo baseplate I believe, so they suggest that you mate these skis and bindings. They are owned under the same parent company, so they are marketing it as a package. But you can absolutely mount schizos on other brands. How could marker market them if not?
And the mounting pattern is probably about the same width, but longer, because the baseplate has to be 6 cm longer than your bootsole length.
