Waist Width: 69
The RS, with its long radius and slender waist, is race-bred high-speed carving ski built for long arcs on hard flat snow. Kastle admits it’s not a big seller in the U.S., but speed freaks and race aficionados will appreciate it. Traditional camber is employed to give it tip-to-tail edge-grip and maximum rebound energy. Kastle’s Elliptical Sidecut is progressively tighter tip and tail, for quick turn initiations and strong finishes. Sturdy vertical-sidewall, laminate construction enhances edge grip. Two sheets of metal keep it damp and torsionally rigid. The Hollowtech tip is a Kastle signature: All but a thin translucent layer of glass is removed from an egg-shaped section of the tip. This reduces swing weight, and because there’s less mass, tip vibration is reduced, both in amplitude and duration, before it can start, so the ski is quieter on the snow and the edges are locked into the snow sooner and longer. Kastle this year increased the size of the Hollowtech oval and says it now cuts up to 15 percent from the weight of the shovel.
