Replying to Need New Skis Please Help

I was at Jay Peak this weekend and there was 8+ inches of fresh snow. I bought a pair of atomic infamous for cheap last year. I found myself spending most of my time in the glades and want to focus more on that. I would like to upgrade to a better ski that is wider and more all mountain freestyle oriented. I would like to keep them under $600 but am open to anything if they are good. I also have marker griffon id 13 to put on them but might need to buy new bindings to fit wider skis so I am open to suggestions on bindings as well.

I am 15, 5'11 and 150 lbs and still growing
I ski mostly glades and a little park
I ski at Stowe, Jay Peak and Loon mostly
thanks
