This may or may not be of any help to you. But I rode them on demo bindings for a few days and I have no clue where they were mounted at, I'd assume they were at whatever recommended is (unless the ski has multiple mount spots on the topsheets...)
But they're awesome, and skied switch quite nicely wherever the ones I had were mounted. Super fun skis. I was on the softer ones cause I'm smaller and they turn very well.
