Bode's skis get pre-tuned at the factory, site-tuned in the trailer at the event or practice site, and race-tuned on the snow just before race. In fact he will bring 5 pair of identically site-tuned skis to the race, and have them tuned slightly differently to account for changing conditions.
Speaking of slightly different, yes, racers are different from the rest of us. They're not worse or better (well some are worse) but different. They bring attention and money to the sport that we love. that's generally good.
The real question isn't 'why Atomic,' it's why did he leave the other guys. Was it the attraction of Atomic or revulsion of something else.
