ARV's rec line aren't very far from center. It's going to cost you for a redrill/mount to get it to center. Griffons only adjustability is in the heel piece, and it's only about a boot size forward or backward, but the toe doesn't move. If you want them on dead center, you will have to remove the bindings, fill the holes, drill new holes over center, and remount the bindings. Like I said, ARV's are pretty close to center already, you won't notice any difference moving your bindings forward a couple of centimeters.
