When you are not in the park, where are you? That is, do you ski the whole mountain, groomers, pow, or what? Almost any twin is designed with jumps in mind.  If you have money, the Karma can ski the whole mountain, its a bit stiffer and wider, if your cheaper the PE is a similar, cheaper ski. The AR6 would be my choice out of the ones you listed. Unless you spend any time in pow the AR6 will never hold you back.
