I think the schizofrantic only come as a system ski setup.
You can mount the regular schizo's on a flat ski.
PS. the schizo system is not a pain in the ass at all. You just turn the pihllips screw with the key provided for you. (Only downside with this binding ive had so far is that the key is plastic...)
^ thank you^ thats what I wanted to know! My ski is flat so I have to install my skis llike a flat ski!
