Perfect North is pretty dope, I grew up skiing there and they always have top notch parks (audition and the mini). And they always get pretty creative.
That being said, you couldnt be more wrong about Mad River Mountain. Every one of their park crew dudes loves to ride, so they take very good care of the parks, even when they are open until 3 am on the weekends. This year things have been super creative, with the lower park being switched up once or twice every 2 weeks. The jump line is amazing at the moment and you cant really beat the length of the park.
I love PNS, its home to me, but right now Mad River has such a better park.
