Yeah I have the 08-09 extremes and some Marker Griffons and I have no idea where to mount them. I would say im in the park 75% and on the mountain 25% of the time.
So please help me out.
i have the same equip as you and i mounted mine 2cm back and they still perform well in the park but im in the powder 70 percent of the time so i would for sure suggest true center mount if your in the park that much they should still perform great all mountain.
