Replying to 4FRNT YLE Mounting Point?? Help=+K

Hey NS,
Planning on buying a pair of 4FRNT YLE's this season because I found a good deal on them. I was just wondering where to mount them. I am 5 foot 11, 200 pounds, advanded/expert skier. I want to do backcountry freestyle stuff like Sammy Carlson and Wiley Miller, while still being able to shred the whole mountain. The recommended point is around -2.5 from true center, but I was wondering if I should mount further up around dead center.
All help is appreciated!! Thanks!!
