yes you can center mount them.
personally, i wouldnt reccommend it, as most of their skis, if not all, are not symmetrical.
the price point park ski MIGHT be symmetrical, but i cant recall for some reason so double check to be safe.
i recommend going something like -2.5 to -3.5 back from true center, or even recommended, in order to get all the magne-traction has to offer.
if you are skiing mainly park, go -2.5cm back from true, i wouldnt go any closer unless they are symmetrical, in which case centering would be the only choice.
hope this helps!
