@chef23 All you have to do is go back and look at the B3 overall list from 2005, 2006. Most of them are not 3 event skiers any more. Heck, some of them are out of the sport entirely. Storm is one of the few active three eventer from that list of the top guys. Real life gets in the way and skiers start to work. Zack, JT, Adam Pickos and Cale Burdick who all skied at this years worlds, were all strong overall skiers when juniors. It is tough to train 3 event as you get older. One of the few who has stayed at the top is Regina. Hats off to her to be able to balance a bussiness, hold a world record in slalom, and still be a 3 event threat on the water.
There is very little incentive to maintain three event for the skier. Look at the Open div overall at Nationals. Dylan, who is one of the best in the US, is only ranked in the top 35 on the worlds list.
