Burton custom vs burton operator?

Im looking to buy a new board im currently riding a ride fleetwood and its great for when im hauling down the hill and because its so wide for my big feet, but when i go to the park its way to heavy to pull anything off. I dont know which snowboard to get because i want to be able to go to the park but the same time be able to fly down mointain and it needs to big wide enough for my size 12 feet, i heard the custom is good. any help is appreciated
