no i dont, but they have to be made custom for a specific stance setup though.
i do know a guy who is setup to make them, but he is pretty busy with another project...something to do with split board bindings.... once that dies down, you might be able to talk him into it. doesn't your "custom" burton (custom like one of a kind, not the model) have voile inserts though? maybe not?
someone should dig up an old thread of burton's (the German guy) with all his crazy stuff in it. i looked for the thread but couldnt find it.
