OK. My fault for bringing my wife into the fray but this is a thread on skiing tuned or un-tuned. I was only trying to make the point that there are different tunes for different abilities/styles and whatnot, but no matter the abilities or style, you are still better off with a tune than no tune. I feel confident in saying I did a poor job of making that point since there are at least three posts about my wife's future ski instruction and not about what the OP brought up - "Is it beneficial to ski with untuned skis?"
I'm probably one of the bigger offenders of hi-jacking threads, but I swear, skiers are the largest population of people with ADD there is!
When it comes to my wife's ski's, I feel confident in saying she will have the best tuned skis of any Never Ever on the mountain, and the skis will be tuned to her abilities. She is already set up for instruction from a very competent instructor who has done a wonderful job in the past in similar scenarios and is a blast to be with. I would even bet they become friends if for no other reason, so they can continue to make fun of me. They are already acquaintances and both are looking forward to it.
So, "Is it beneficial to ski with untuned skis?"
