ways to ski bumps
I took a clinic with "rippin old guy" and we skied bumps various ways, including "around the bumps" and zipperline/world cup.
however, in the around the bumps style, the skis still kept snow contact, the turn starts on the side of the bump, ie the same techniques, different line, different radius turn
in the zipperline approach, the analogy of your head being attached to a zipperline, taking a straight path from A to B, was emphasized.
this was presented as the highest technical level of mogul skiing.
When done correctly, much of the impact (in zipperline) is due to the speed of hitting the mogul. So where does the energy go:
into the shovel of mogul ski, which is very flexible,
into the ankle absorption
(with a tall(ish) stance, using skeletal alignment, not muscle strength)
some flex in the knee
When the skis remain in contact with the snow, this tells you that the impact is being absorbed/managed very proficiently (otherwise the skier would get "air")
As others have said many skiers "take" the zipperline, but dont actually manage to stay on the snow. The phrase "Its easy to go fast" was repeated all day long.
In Reillys skiing, he takes a rounder line, and does it extremely well. Most skiers who take this type of line have all sort of technical troubles: overturning, hands, back, no extension, etc.
If i could ski like either of em, I'd be happy. If i could only ski like one of em, I'd take the old guy
