If you follow the WC DH/SG, you may be familiar with Canada's John Kucera, who after winning the World Championships, crashed at Lake Louise with a nasty compound tib-fib break. His comeback story is fairly normal, about hard work, determination and passion to get back into the game, but unfortunately while forerunning a race in preparation he broke his leg again. What really caught my attention in the article here http://www.theglobeandmail.com/sports/more-sports/forced-to-the-comeback-trail-yet-again-proves-there-is-no-quit-in-kucera/article6219110/ was Kucera's quote on how he broke his leg the second time:
“Atomic had come out with a new binding and hadn’t worked all the bugs out,” Kucera recalls. “I came into a turn and walked out of my bindings on my good leg. That [crash] really messes with your head. It takes time to trust your gear again.”
No kidding that would mess your head up, especially as a speed skier. If you don't have complete trust your equipment at 100+ km/h, your in deep trouble on several levels.
