Hey Alpacaa, Matt, Rossi TM here.
Most of the team (Parker White, Chris Logan, Xavier Bertoni to name a few) mount all of our S-Series skis are either dead center, as you ask, or at 1 cm behind center for just a little more tip pressure while skiing switch. at 1 cm behind dead center most of the crew feel skis ski the best, dead even swing weight and a little more tip to balance on.
