Replying to Change bindings and mounting position?

Last season i bought Faction Prodigy 2.0s with some cheap bindings cause i couldn't afford better ones.
I skied all mountain most of the time bc we didn't have a local park so i got them mounted on the factory recommended "Progressive" which is -7cm from true center, bothered me a lot when skiing. This year i am switching resort to only skiing park and wanted my bindings more in the center. Should i switch bindings to a pair of Look Pivot 12s and mount them -2.5 from true center? I am worried that the old holes from the previous bindings might cause problems and harm my skis durability. Thanks
