make sure you sign up for some english classes too, cause that was one of the worst sentences ive ever heard. youd best be from a different country (then its ok).
Otto Wiest took the first design for a parabolic ski to Head in Austria at least 5 years before Elan came out with the SCX. They couldn't understand and were reluctant to try a new ski design. I don't know how this can be documented, but I know it happened.
Otto was one of the first ski instructors in Vail when it originally opened. He is a genius. Otto would crack up that he is getting props on NS.
parabolic sidecut is different than regular sidecut. I do believe that snowboards had sidecut first, but parabolic arc edge profiles first appeared on Elans.
I have a pair somewhere, and have skied them. they are pretty sick little skis
