Replying to Looking for a east coast pow day ski

as the title says i'm looking for a fattie for when the east coast gets their 2 foot dumps. Last year there was 6 of them that i wasn't feeling to comfertible with my park skis. So what do you suggest. I'm 6'2" 180 pounds and a pretty good skier but have absolutly no pow skills. So how fat should i go. I met a guy at sugarloaf who was probably 220 pounds and riding seths with a 90 something waist. He said that he had to get going fast to float but otherwise he loved his skis. This guy was legit. Also becasue i'm on the east coast i would the ski to be able to be an all mountain ski. So if you guys could suggest a ski that would be great or at least throw out the width i should be looking for.
