I have purchased a fair number of new skis in the past few years and I am constantly amazed at the base/edge prep that they are sold with. Now these are high end skis from a number of different manufacturers. They range from fair to truly awful. Not even a pair that was good, not one.
Now if I was looking to sell high end skis, I would want to make a great first impression on the snow. If you leave the shop where you bought the skis and they didn't tune them, you will be disappointed with their performance. Ad depending on where you buy, they might not even be able to tune them properly. Same holds true when you demo. You are at the mercy of the rep and how he treats the skis. It can be the difference between "I love them" and "I just ain't feeling it"
If a ski retails for say over $700, why can't it come ready to ski? It's not that I mind doing the tunes, I don't. And you would have to do it down the road anyway to maintain the skis performance. How is it that the skis makers ignore this very important detail???
