actually, every ski is butter-able, some skiis require different techniques, but i can butter my cousins white and black mad trix, i have never used a ski i couldnt butter, some skiis require a slower lean forward to flex them right in from of the toe, and others you need to throw forward to make it flex throughout the whole front of the ski. i have even buttered my buddies brand new rossi GS world cup skiis and they were the hardest, but still butter-able.
