BD updated the Amperage for 2013/2014, adding sidewalls and stiffening the tail. It maintains a 115-millimeter waist as well as tip and tail rocker. Highest tester scores were for flotation, and lowest for carving, though they felt the AMPerage was slightly more versatile than the wider Megawatt. “Super skid, not much carve,” Attridge said. “This ski is quick, light and easy to throw around in all conditions,” Witman added. “Tips chatter at speed, but the lightness also helped the ski stay on top of the snow.” Construction includes a poplar core, torsion box construction and Formula One Technology, which adds ribs to the top of the ski in strategic areas to retain rigidity while reducing mass. “Crushed the pow and nailed the landings,” O’Neill said.
