A lightweight carbon build coupled with the fattest shovel in the test equals exceptional flotation. In powder, the Insane’s feathery feel and long-radius turns are, well, insane. Plus: The ski’s weight-to-width ratio is ideal for setting the skin track. Minus: Gets tossed in the crud; too fat and light to plow through it. Tester’s Take: “For backcountry enthusiasts who seek out the deep.” —Casey Day
