Which twin tip skis should I buy?

I ride both the T-hall and the AR6. I like the ar6 much more for the all mountain riding. Much more stable at speeds. The T-hall is fun in the park but can get a little squirrelly at speeds. At 200 you shouldn't have any trouble pushing the AR6 around. That being said the T-hall rips and is a great ski for the park. Its up to you, they will be on your feet.
