The ultimate goal in bumps would be to ski in the zipper line. Its more like a "commitment" than anything else. That's why you sometimes find great skiers that cant ski bumps in the zipper line. They lack commitment. The other thing is you need to be very quick in your feet and you need to be fit. Skiing bumps and especially skiing them in the zipper line is very exhausting. Good mogul technique makes it easier but its still a discipline full of flexing and extending and hard impact. In short, its a workout. And its bad on your knees and back. I don't recommend it but I still do.
That said, I was never a good zipper line bump skier. My interest was to ski all over the mountain so I deviated towards all mountain skills and skiing. But I cracked the bump skiing code, "line selection". You have two basic concepts in bumps: maintaining a steady even rhythm and using the bumps to turn on. In modern WC zipper line racing they have solved this equation by spacing bumps evenly from top to bottom. This way its possible to ski down the zipper line turning on every bump in a steady even rhythm. The challenge here is to do it as fast as possible. However, that is not "our" challenge in bumps. At least not mine. I can take as much time as I want and I can turn when I feel like it.
So what I do is I scout for places to turn. Instead of trying to find a zipper line I traverse skipping bumps looking for a good place to turn. Once I find a good place I turn and go back the other direction and repeat. While doing this I comfortably make my way down a mogul field without any risks. This is actually all you need to ski in moguls. Take it slow and take your time. Stop when you feel you need a brake but here we come to a very important issue. Keep on going. Don't stop if you don't have to. This is part of the commitment, keep on going even if its slow. You cant be defensive or hesitate. Be confident. Stay in the fall line, don't rush your turns. Scrub your speed off at the next bump.
Next step is to turn more often. Instead of making a turn and then traversing back, make two consecutive turns. Then traverse or skip a bump by going sideways. Then make three turns then four etc. All of a sudden you find yourself making short burst in the zipper line. I often hear that you need to look ahead when you ski bumps but IMO its highly overrated. I usually just look one bump ahead. It really doesn't matter what's ahead. No matter what it is I eater turn on or around it or traverse away from it.
To take it to the next level of commitment, stay in the zipper line no matter what. Here you also don't need to look more than one bump ahead. Great mogul skiers don't need to look far ahead. They are fearless and they know whatever is ahead they can deal with it. However, there is nothing wrong with looking ahead. You can do it but remember that part of the fun with mogul skiing is you never know what's ahead and part of the challenge is a spectacular recovery. This doesn't mean that you should kill yourself. Once you think you cant stay in the zipper line STOP. Preferably one bump ahead of crashing. Traversing is for sissies like me. True bump skiers never do.
jc-ski, thank you for the videos of Jerry Berg. Fantastic skiing. And a very good tutorial. Its still all you need to know in that video. Good short turn, flexing and extending and line selection. Perfect stuff. Stuff the skiers in the original video would benefit greatly from. On the other hand, they pretty much nailed the fun factor and that is something we should never look lightly upon. The photos tball snipped were photos each and everyone of us would love to have of ourselves, right guys? It doesn't get much better than this, cool factor 10:
