Just returned from 4-day hike in the Adirondack High Peaks -- Wright, Colden, Algonquin & Iroquois. Denali Ascents proved perfect for 90% of activities on this trip. Worked remarkably well above the timberline traction-wise, but less so floatation-wise in powder in the saddle between Iroquois and Algonquin. Purchased the tails but haven't used them yet. Managed to lose a strap when it slipped out of binding buckle, but believe that can be corrected by leaving closer to a 2" tail outside the buckle. Otherwise, very happy w/ ease of binding system and quality of shoe. Don't look to hold conversation on the trail w/ these -- they are noisy in anything but powder.
