Replying to K2's what to get

I've been looking at different k2's, and am interested in the Sights, Domains, and Iron Maidens. Price plays into it quite a bit, may sell my current setup and hope to get enough for at least the bindings, but if I had my choice, and enough money I'd go straight for the iron maidens. I'm 6'3 160 lbs. and an intermediate/advanced skier, I'm aware that the largest k2 size is 179, but measures larger. Inb4 hate on wanting a proper sized pair of skis. I'll be doing 75% park, 25% all mountain, and I live in the northeast so pow days aren't completely unreasonable. I'd just like some advice on which pair people have had the best experiences with. I've only ever heard good things about all three, and am skiing on 2012 after bangs so any of them will be an upgrade.
