Replying to Full tilt tw pro or first chair 6s?

i wanna get the tw pros because i ski mainly park but will ski pow or groomers if it snows(east coast) but they're more expensive than other full tilts. the first chair 6s are the same flex but are used mainly for all mountain and pow. how would the first chair 6s hold up in the park and would they be comfortable hiking rails and is it worth it to spend the extra $60 to get the tw pros? should i get the first chair 6s over the tw pros?
