I've been having a tough time getting used to early rise and the difference between contact point when flat on the snow and contact point on edge. When I had the bindings put on, the shop wanted to detune about eight inches down. I never detune any of my other skis and I had a fight with them about it. Picture two young shop guys fighting with an old lady.. Anyway, took them out the first run, not the ideal conditions, got on a firmly-buffed cat track, and the skis suddenly engaged rapidly and I took off up an embankment. So, I took them in, had the side bevel changed to what I normally ski, still no detuning, and went out again. Same issues, but better. It was end of season, so I just changed to my old skis and decided to do a complete tune on them myself before the next season so at least I would know the results of each change.
Sharpened them myself and then initially detuned then back to the contact point when flat, but lightly. Thought about it a bit more, and above the contact point when on edge, increased the base bevel a bit because that hooking really worried me. Took them out this season and discovered:
1 - Main issue is they are just DIFFERENT from my old skis. They like a slightly different balance point and they turn totally differently from my other skis. It took me weeks to get it right, while I LEARNED to love them.
2 - I'm gradually moving the sharpness forward and no longer detuning them.
3 - I am now having almost as much trouble going BACK to my other skis as I have adapting to these.
I think some of us have issues adapting to new skis with radically different technology, shape, stiffness, width, length, and tuning from what we are used to, and we have to spend time with a ski before we should blame our problems on the ski. And personally, I wouldn't trust a guy in a shop unless he/she was my clone. In fact, based on what I've heard on this forum, they may not do what you tell them to do or even what they tell you they did. I could tell when I started working on these things that the guy who changed my bevel had winged it free hand as the bevel wasn't constant along the edge, for instance.. I'm in search of a shop I can trust again.
