Head Oblivion 94 mount point

Hi collective. Just in time for snow levels to soar to 8k feet at the local hill, I'm mounting my (son's) fucking skis tonight. I picked him up a pair of Head Oblivion 94s on last season closeout. I see a 5cm spread between "ski center" and "all mountain" stamped on the top sheet. My son is not a dedicated park skier or anything, just strong intermediate recreational skier type. He would say "huh?" if I asked him "do you prefer a more centered stance of more directional". I'm leaning towards All Mountain as it's probably a more familiar feel for him but figured I'd check if anyone has specific experience with the ski and can comment. thanks.
