I got the AR7's this year, and I have been blown away by their performance. Granted, I ski about 70-80% park and do like to do some woods/groomers on occasion, but they've torn up anything I've tried so far. As far as park goes, since that sounds like what you're most interested in, here's my thoughts:
They're nice and stiff for a park ski, which means they're really stable at speed and on landings. It took a little while to detune the edges but once I got them rounded down they've performed really well on rails as well. The swing weight is pretty light for a relatively long ski, so spinning feels pretty natural.
My only two minor complains are the asymmetrical tip/tail (the tail is much skinnier than the nose) makes riding switch feel a little awkward, but that could be since I'm used to perfectly symmetrical skis. Also, with the stiffness of the ski comes more difficult buttering, but that's a tradeoff you'll make with any ski.
Overall, they're a fantastic ski from what I can tell so far, and I would absolutely recommend them... ESPECIALLY over suspects hah
