Some folks argue that we ski more cement than powder here in the NW and for cement (if now also powder) moving the binding back is recommended by some folks. I just moved my binding back 2cm and we'll see how it does at alpy tomorrow. I'll let you know.
-ShredTheGnar-Hellbents are +3.5 back
9th rorys were +7 for big mountain but remounted them at +3.5 as well.
People saying true center, its only good if you have a symetrical ski or you purely doing BC jibbing.
