Replying to 08 Seths

I know its early to be thinking about what skis to get, but i dont really care.
I want to get a pair of fat skis next year for the ocasional powder day and just to mess around with. I really like the look of next years seths but im not sure about the rocker. Im 61 175 pounds and i know that the rocker decreases surface length so idk if the 179 would be enough ski out of real deep snow. I ski really tight trees alot so i dont want tehe 189.
Any input from others who have actually skied a rockered ski, will the 179 feel really small for me?
