Thanks for your answers. I think I got a good mental picture how to ski both ways now. Can't wait to get to some moguls and try it out.
I have ordered this mogul instructional video. http://www.youtube.com/watch?v=rRSQRtmId3w&feature=player_embedded#
(sorry about the swedish)
It seems more oriented towards the traditional technique, but they also talk about more carving and something that resembles QCT.
If you look at 3:05 you can see how they teach you to "slide" sideways down the back side of the mogul with your skis pivotted. Its easy to see in the faster clips as well. You dont want sharp edges here so take your old trusted worn park skis. They also tell you you should hit the next bump with your entire foot as you are finished sliding. This is the reason the zipper line evolves to become a rutt. The more skiers that ski this exact same way, scubbing snow off the back side of the bump and compress it into hard snow against the next bump, in the same zipper line all contribute to making it deep and hard and more straight and faster and more slamming and more hurting and more demanding. What they teach in the video is the traditional zipper line skiing. This is not over the tops.
I dont know why over the tops is called a technical line or why people think its with less impact. Its actually more impact. The only exception is that the impact in the over the tops method takes place on the front side of a mogul that is loaded with soft fluffy snow insted of a hard icy rutt. Its also your ski tips that are going in first and your skis will bend and absorbe the impact insted of you slamming sideways into the rutt with with your feet. Ouch ! See my previous posting. In engineering we call it "jerk".
Here is the wiki for jerk:
Jerk is often used in engineering, especially when building roller coasters. Some precision or fragile objects — such as passengers, who need time to sense stress changes and adjust their muscle tension, or suffer, e.g., whiplash — can be safely subjected not only to a maximum acceleration, but also to a maximum jerk. Jerk may be considered when the excitation of vibrations is a concern. A device which measures jerk is called a "jerkmeter".
Jerk is also important to consider in manufacturing processes. Rapid changes in acceleration of a cutting tool can lead to premature tool wear and result in uneven lines of a cut. This is why modern motion controllers include jerk limitation features.
Ok, qvasi translated into mogul skiing: .... Jerk is often used in skiing, especially when skiing bumps. Some precision or fragile objects - such as mogul skiers and especially their knees , who need time to sense stress changes and adjust their muscle tension, or suffer - can be safely subjected not only to a maximum accleleration, but also a maximum compression.
Have a go at the other paragraph....
