Kills the whole mountain!!!! From grooms to pow they are perfect. If you want to train for next years slope style park event meh, wouldn't recommend them for that purpose. But if you want to cruse the park and trow down some 360 and flips, its defiantly doable. I have my 2011 kung fujas as the ski where I'm not quite sure how the snow is out on the mountain, like if there is any pow or not. if there isn't, then i always still have a really good time.
get them.
