I agree. A lot of shops still detune as a matter of practice because the beleive (probably correctly) that most of their customers on modern skis still skid their turns the old fashioned way. It's a shame because it takes much of the performance away from those new skis that someone just spent mucho $'s on for little good purpose. At least the shops should check with their customers first.
If a person wants to avoid this tragedy, the best assurance is to take their skis to a shop that tunes a lot of race skis. They survive on their reputation for tuning skis properly.
It might help to leave a note taped to the ski to remind the tech of how you want your skis tuned. But many techs at regular ski shops tune all skis the same regardless.
Mogul skiers and extreme skiers may have specific reason to detune. In powder it makes little difference what shape a skis edges are in (except that you may still need to get to the powder). For everyday skiing on hard snow it makes a world of difference.
When I need to take my skis to a shop, the Race Place in Bend, Oregon is one of two shops in the PNW that I take my skis to although I suspect that that there are a few other shops that can do the job properly.
