well your not fucked by any means, mounting at recommended will work, u can have them remounted almost definitely. you by no means have to have the ski center mounted to make rails and jumps easy. in reality you should put your ski on a table and look at the sidecut wherever it is the highest point is going to be the balance point of that ski, usually not center unless the ski is symmetrical so in reality mounting some where between center and recommended will give you the best performance overall.
