You should really think about how much time exactly you would spend in the park..a lot of people tend to overestimate, and also keep in mind that, youi'll be skiing regularly on your way to the park too, so unless you really plan to spend your day there, don't go true center. As nomensteven said, it really does affect your edge hold and all that, but that doesn't mean you can't turn with them, they just tend to skid and slide around a little bit more, if you have them true centered, don't worry because you'll adapt to them. Although it'd probably be a good idea to mount a little back if you like charging
