I think all the core work and balance training are great. But, I also think that skiers underestimate the need to have a good aerobic base. Itri hinted at it when she said in her post that her bump performance improved after doing tris. I found the same thing happened to me after I started training for tris.
Even though skiing is anaerobic, performing well at altitute, lasting all day without tiring or soreness, and doing top to bottom bump and powder runs without stopping require endurance. So, I'm a big fan of long-distance road work (running and cycling) and long-distance swimming, and adding biweekly interval training in all of those disciplines. Combine that with 3x a week of varied strength training (mixing up whether you use bosus/swiss balls or stand, and mixing up numbers of reps and amounts of weights to variously work on power, endurance, and strength) and you're golden.
