The fattest ski in LX family, at 92 mm, is almost exclusively sold in the U.S., Kastle says. It's embraced in particular by women who ski Western resorts and expect to encounter plenty of powder and soft-snow conditions. Kastle's LX line of all-mountain, frontside oriented skis is designed to suit the needs of skilled but lighter-weight experts (particularly women) who don't have the heft -or carry the speed -to sufficiently bend the stiffer skis of Kastle's MX line. The LX still gets two sheets of metal, but Kastle gives it a thinner profile to enhance flexibility and reduce weight, adding an edge-to-edge cap of glass over the wood core to keep it torsionally stiff. Traditional camber yields snappy response and positive tip and tail pressure. The rounded tail releases more easily than the square MX tail. 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, 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.
