I bought some new in the wrapper "classic" 90's slalom race skis, because I really like to run a long skinny ski sometimes. I was in a hurry to try them out so I took them to a local ski shop that has been in business forever to get them mounted and tuned. Went through the normal game of 20 questions and went back to pick them up a couple days later. Took a quick look at them to make sure they were sharp and had some wax on them.
So, the next day I head out to the local ski area pop the new skis on and go for a run. Put one on edge and it takes off on me, repeat a few more times with the same result. I'm thinking, jeez I've really become dependant on shape skis, can't even turn a set of "real" skis any more.
Then it occurs to me to check the edges to see if the tips and tails had been de-tuned - nope, razor sharp tip to tail. Went in to the slopeside tune shop and begged the use of a stone, detuned about 10" tip and tail - amazing they turn like skis;)
So this morning I email the ski shop that did the tune and ask them why they didn't detune like they are supposed to. Guys response is that if you check level 1 they detune 3-4" tip and tail, level 2 just a couple inches on the tail and level 3 no detuning. I said, sure for a shape ski but how about for a straight ski. It seems that he was un-aware that the process was different.
Learned my lesson, nobody touches my Atomics after this unless they are 40+ ;)
