the training market. By the end of the year the improvement of the "parabolic" design was obvious to everyone, and the SCX was named "ski of the year" in the trade press. By 1995 older designs were being sold off at pennies on the dollar in bargain bins as skiers turned en masse to the new designs. By 1997/98 the conversion was complete, and only parabolic designs were being produced. Over time the name of these skis changed. Originally termed parabolic by their designer Jurij Franko, the term carver soon became common as these skis were being sold largely on their ability to allow even beginners to perform the efficient carved turn. This changed again to shaped ski by the early 2000s, as the design was applied to a wider variety of ski types and some level of parabolic shaping became universal from training skis to downhill racers. Variations Different types of skis have different sidecuts. Skis with drastic sidecuts tend to make quicker sharper turns and have a smaller turn radius. For example, a world cup slalom ski would have an extremely large tip (probably around 120 mm) a narrow waist (in around 60mm) and a large tail (slightly narrower than the tip). The drastic shape of this ski would allow it to make extremely quick turns (radius between 11m and 14m) without skidding. The disadvantage to a pronounced sidecut is that the ski will be less stable at high speeds, preferring short, quick turns. Also, skis with a drastic sidecut will perform poorly in moguls. Most skis have a moderate amount of sidecut. This allows reasonably fast turns (radius around 17m on most skis) while still maintaining some stability at higher speeds. Another possibility is a very slight sidecut. This is commonly found on giant slalom skis and competition level mogul skis. The straighter sidecut allows skis to make long, fast, highly stable turns (radius around 30m for giant slalom, even more for most mogul skis). In mogul skis, the narrow width, straighter sidecut, and light weight allow the ski to be maneuvered through the tight troughs in the bumps. Jumping skis are very wide and have virtually parallel sides, as the ski jumper is more concerned about maintaining a fast and straight trajectory, and not turning at all. As powder-specific constructions are becoming more popular, some extremely unusual sidecuts are beginning to appear. For example, the K2
