Replying to Coreupt Yards work well in park?

Well this year is my first year of park skiing, and I was wondering if the skis im using would effect my riding. My setup is the 2012 candide yards from coreupt(182), marker squires, and nordica cruise boots. I find myself having a hard time do 360s because of length, and i was wondering if I should just keep trying or if I should find some shorter skis that are geared more towards park. If anyone uses these skis feedback would be appreciated and keep in mind im new to park and if I say something stupid thats why.
