Yeah, it's not the ski - it's a common misconception: it contributes, but little. It's the energy from the impulse of the turn, virtual bump, body compression, counter, coiling etc. If you time it right, it feels like the same thing...
Wow - that's quite the stroll down that lane... good memory, James!
There was so much controversy at the time, I also made this one:
The thing was not having anything under the middle of the ski, where you normally have the ice/snow etc... but even so, a 3" bend is WC territory!
The other thing that came out of those tests, that I did not capture in the videos was that you can easily overpower the outside ski and eliminate that small pop with mistiming the release - even with a tiny mistiming, it was easy to kill any pop from the ski.
