No worries. Back in the day we all started with standard mount. Destroy them...slay everything with no regard for you skis. Ignore the giggles from the spoiled kids and stomp every trick you can. Shut their mouths with you skill.
Once you have broken them, remove the bindings and find another pair of cheap ski and mount them however you want. Park skis don' t last long if used properly. You will have many pairs come in and out before your done.
