If Kastle athlete Chris Davenport was still skiing New Hampshire hardpack instead of Aspen powder, the FX84 might be his everyday ski instead of the FX94. It's lightweight, but metal gives it integrity, and the 84 mm waist--not too fat--keeps it quick from turn to turn and grippy on hard snow. It weighs 3,750 grams per pair in the 184 cm length. 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.
