Bindings, where?

no - it's not a fully symmetrical twin and (correct me if I'm wrong) I doubt yous pend 50% of your time riding switch. Most park skis will mount 1.5/2 back from centre. The fact you didn't ask for these to be centre mounted when you bought them also kinda hints that for you you're better off not centre mounting them.

leave them where they are

people on this site make it sound like you have to have bindings center mounted to ski park... you MIGHT want to center mount if you ONLY ski park or know for a fact that you strongly prefer center mount (or just hate turning or skiing soft snow well)

Lots of rail oriented skiers mount center on non symmetrical skis. Will Wesson comes to mind. I have my old dollos center, love them. Spend a pretty even amount of time switch and forward. If you don’t think your missing anything just ride em. However I don’t agree at all with people who say an asymmetric park ski at center is bad, have been on many pairs and wouldn’t personally do anything else if the ski will be used on rails primarily. Ice coast and old so jumps can go fuck themselves until spring.

even if the skis were fully symetrical your body geometry is different. You lean forward when you ski regular. lots of people lean foward when they ski backwards to. I cant imagine anytime where you should mount true center. I usually like to go 1.5 - 2.5 back from true center. Lots of skis these days have multiple mounting points for different types of riding recommended from the factory.
