The XX90 James is designed to be the everyday-commuter twintip for all-mountain new-schoolers who spend as much time on and off trail as in the park. Unlike the XX80 Colby competition ski, it gets a dose of tip rocker (170 mm high, starting 340 mm back from the tip) to smooth the ride in rough snow and terrain. Kastle's new XX series of twintips is built around park-and-pipe athlete Colby James West, who participated in its design. It represents Kastle's first real foray into the new-school world. There are three models--called Colby, James, and West--with waist widths of 80, 90 and 110. They're all wood-core, metal-free, vertical-sidewall laminate constructions. All have symmetrical sidecut and are center-mount-ready. Both tips on all Colby James West skis feature Hollowtech technology, 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.
