The Kung Fuja's is an all-mtn/powder ski, if you're not going to be in the park at all recommended (traditional) is where you want to be mounted. THAT'S K2's RECOMMENDED
MOUNTING POSITION, the tech was correct in recommending traditional.
Just because you're an ignorant little scumcunt and didn't research what mounting position you wanted before you bought your skis does not give you the right to harass or take it out on the tech or the shop.
Also, I'm willing to wager that you couldn't tell a difference between skiing the Fuja's mounted 0 or +2.
