Niether of these skis are going to be the one for you......I would go with the Fischer Kahua its got a park heart but you can still mash is in the backwoods
Fischer is going to be far more durable and it will be a little stiffer so you can ski it outside the park if you really wanted. WAY CHEAPER cheapest twin tip you can get......
If you can hold out for one more year next years addicts are going to be even better because we are coming out with a pro model that will ( I think) keep up with and may possibly even rival both of the AR5 and the t-hall
