Testers gave the 80 millimeter-waisted KOA 80 high scores for versatility and playfulness. "I liked the tip profile and progressive shape. It doesn't have a race-ski feel, more freeride," Gleich said. With an easy flex and tip rocker, the KOA 80 was designed for intermediate through advanced skiers who mostly ski the Frontside with occasionally forays in to soft snow. Muecke called it "soft, playful and easy to initiate." Construction includes sandwich sidewalls, a poplar wood core and a layer of lightweight, yet strong carbon fiber from the aerospace industry designed to keep weight down without loosing liveliness. "It's lively and soft but can be a little chattery at speeds," Muecke said. "It's appropriate for a wide range—beginners through advanced skiers."
