Depends on how much you weigh. P10's will work fine for park, some people like the lifter on, if you buy them with a lifter, some with it off. The P12 Jib is just the P12 with no lifter on it and Troublemaker graphics. They are the same binding with different springs for different DIN tensions. If you are lighter, go with P10's, if heavier, go with P12's.
