Skis this wide (104 mm) are typically metal-free and rockered, but while the FX104 may have the width of a freeride ski, it favors a more technical and aggressive style of skiing, thanks to traditional camber and two sheets (albeit thin ones) of metal. It weighs 4,400 grams in the 184 cm length, making it a logical choice for freeriders who spend as much time touring as riding lifts. Kastle's FX line, unchanged from last year, is built around--and with design input from--ski mountaineer Chris Davenport, who typically mounts his skis with Dynafit AT bindings. In relation to the super-light, tour-oriented TX line, Davenport's constructions are sturdier and metal-reinforced for reliable downhill performance even in difficult snow on difficult terrain. There are three FX models in widths of 84, 94 and 104 mm. All are wood-core, metal-reinforced, vertical-sidewall laminate constructions. All feature standard camber for positive tip-to-tail edge-grip. The tips are slightly tapered, so as not to be nervous or hooky in the steep, technical situations for which the FX is designed. Both the tip and the tail of all FX models feature Hollowtech, which 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.
