Replying to Skis for christmas, HELP

So after three years of funding my ski ventures on my own, my parents have decided that skis and bindings for christmas are an appropriate present.

I want to get some good skis that will last, but at the same time I need to be somewhat concerned with price.

I have skied on 09' 169 k2 silencers with px12 jibs for three years now, and they are delamming, edges tearing out, and the bases are totally shot.

I ski mostly park, but I love shredding the pow and trees whenever it comes down and I happen to be at the resort. (Screw you east coast winters!)

The only thing i've even really considered is the 2012 domain with free 10 din binding that the house boardshop is selling. For the price, $575, this setup is definitely around my appropriate range.

It seems like an awesome soft jibby ski, and flat camber definitely interests me.

So my question is this, should I go with this deal despite the limitations of having a 10 din binding? And potentially being stuck with a 169mm ski again? I currently ride at 8-9 din all around on my px12s and am concerned about not having a large enough din range as I continue to progress.

I'm 6'1, 165 lbs athletic build.

Some other concerns of mine are that I need a longer ski than what I have been riding since I started skiing, that a ski like the domain will fall short outside of the park, and that I am potentially missing out on a whole range of ski flexes. IE: stiffer skis

I have tried in vain while browsing for skis thus far to find a park ski from a few years past that would fulfill what I am looking for, and it seems like my only options are for new full priced skis.

I need some help NS! Only a few days left to pick a ski in time for christmas delivery, I may seem set but any and all input is appreciated!
