I did. Actually, as much as it sounds like a ridiculous claim, it's not far off even though I don't really think I invented it. We were testing Volants years ago on a decent pow day at Squaw, and I had an old beat up, bent pair of Chubbs that we were using as a reference for new models. At the end of the day we were discussing what we liked best, and I said I actually liked my old bent pair because they floated best.
McConkey immediately realized that totally made sense and immediately started thinking of a rockered ski, and since that day he's credited me with coming up with the idea of rocker. All I really did is recognize that it worked better than cambered skis--it would take his forward thinking mind to actually put the idea into action.
People could get technical and say he didn't actually invent it because there were rockered snowboards and other things back in the 80s, but did they last? No. McConkey gave rocker to the snowsliding world and if you ski or snowboard on something with reverse camber, it's because of him (certainly not because of me).
