Another cool topic to do would be to show how the development of twin-tip skis has helped to revive the ski market by getting younger skiers off of snowboards and back on skis. I'm sure you could find at least a few articles relating to it, show how more and more companies are building twin-tip models; there are graphs out there that show that for a short time snowboarders outnumbered skiers on some mountains, but the trend has swung back to skis; and then for good measure, at the end show a clip from Propaganda or another movie, summarizing how skiing has progressed.
