I am trying to decide what to get...I am torn between the Line SFB, K2 kung fujas, and the Line Opus. I ski out west twice a year about 15 days and the about a week on the east cost. I currently have the Rossy Scratches... What do I do? I found the 2011 Kung Fujas brand new for $399....should I buy these and the Opus? Is there a difference between the 2011 and 2012 Kung fujas?
