Replying to Skis for my buddy

Hey guys,

Finally convinced my buddy to get a pair of twins. Hes just starting out in the park but is a relatively good skier. He's about 5'11" and around 180lbs. So im thinking prob around 170-174cm skis, right? He's looking for twins that will be really solid in the park/pipe, but also able to tear up all mountain. Also, they have to be durable as hell, cuz hes known for trying dumb shit. So around 60% park/40% all mountain.

I was thinking K2 Extremes and possibly, if money isnt an issue, Volkl Bridges.
 
Thanks
