this like 1 or 2 cm behind true center. I've heard that center mount and rear mount feels kinda the same, only time i plan on mounting back a little is if my skis aren't asymmetrical or if i plan on riding pow. Which is when the marker schizo ends up being really nice since you can move the binding itself about 3 cm back or forward. i plan on getting schizo's next year or what ever replaces the schizo
