The verdict mostly depends on how much those 3-4 hours of pow are worth to you.
There's a big variety in rockered skis out there, check out TGR for good discussion therein. Spatula/Praxis/DP138 are more heavily rockered and more pow only. Other models like the DPSkis Lotus 120 are a bit more versatile. I've been lusting after a pair and am really considering the 200cm, but the price(~1k) is nuts. Instead I bought another "traditional" pow ski = 109cm waist for $80
