I recently purchased the Surface One Life powder ski. 189 140/112/132 with Marker Griffon bindings. I wear the Nordica speed machine boot. I took them out for their virgin run last week. Deep powder day here in Utah. In the pow they were as good as advertised. On the groomed down right bad. Bad as in I could barely handle them. I was bouncing trying to make very basic high speed turns. I've skied for 24 years. Its been 20 years since I had a ski I couldnt handle. I'm 5'9, 180lbs. I was aprehensive about going with a fat ski. I have to be missing something. I'm told the length may be longer then I can handle. Given the fact that I've made the purchase is there any adjustment that can be made away from purchasing a shorter version or chainsawing them down to size?
