I am a racer and i have to tune my own stuff, if i didnt then i would have to go to the ski shop every race and get it done for like 20 or 30 dollars. that is expensive for the whole season. So i have all this tuning stuff and i tune my twin tips too. i tuned my old 1080's like i would a race ski, so basicaly my old 1080's had a race tune on them most of the time. I got new twin tips and i was wondering how i should tune them differently than my race skis. If this helps the new twins i got are the 04 scratch fs (168) and i use them mostly all mountain about 70 percent in the park in the park and pipe. Thanks.
