If you want a twin specifically for the park and bumps, get the 1080 Mogul, since that is what it was made for. There shouldn't even be a question there. You get a ski that is built for the task you want it to do. The best thing in your case would be to build up a ski quiver (since you seem to want task-specific skis). That is, get a mogul ski, get an all-mountain ski, and get a powder ski.
