Like the Experience 83, the 78 features Rossi's Central Sidewall construction, with strong, edgy vertical sidewalls underfoot and less grippy cap construction toward the tip and tail for enhanced forgiveness and better performance at low speeds. It's sold as a system only, with the 10-DIN Xelium binding. It's part of Rossignol's All Mountain collection, designed for maximum versatility in all the terrain and snow types that resort skiers encounter. Waist widths vary widely in the series, from 98 mm in the flagship model down to 74 mm, with target abilities decreasing with size (fatter models for experts, narrower ones for intermediates). All feature Rossi's Auto Turn Rocker - early-rise tip and tail for shock absorption and soft-snow float, camber under foot for hard-snow carvability. Extended Sidecut moves the widest part of the ski beyond the fore and aft contact points: The ski won't feel hooky or unmanageable at low speeds and edge angles, but when pushed to higher speeds and edge angles the sidecut engages more edge for maximum stability. All are wood-core, laminate constructions with reinforcing laminates of different weights and densities, including metal (Experience 98), basalt (88 and 83), carbon fiber (78 and 74) and aramide fiber (76). All have vertical sidewalls (with the exception of the Experience 76 and 74) for maximum transmission of energy to the edge. Most also feature Rossi's distinctive Cascade Tip design: like a leaf spring in a car, the ski gets thinner, lighter and more flexible near the tip, reducing swing-weight and promoting easy turn initiation.
