I just got some 185cm Alp Tracks 106s a few days ago, mounted them with Plum Guide toes, Kreuzspitze GT heels, left the factory tune alone, and took them to Mammoth Mountain to test them in the 2+ feet of spring snow they just received. I'm skiing them with Alien RS boots. These are just initial impressions and I'll try to post more after I get some more days on these things in their element. I wasn't sure for a minute if I wanted the size 185 or 177 at 6'0'' 175 lbs, for use as dedicated backcountry long-range powder seekers. Normally 185 would be a no-brainer for powder but its always nice to save a little more weight and fit in tighter spaces if you don't give up too much float. After some good advice from skimo.co (basically that they are not super demanding skis and I couldn't go wrong either way), I decided to embrace the quiver role and try the 185 for max float. When I first unpacked and flexed the skis I thought they hand-flexed very stiff underfoot and in the flat-ish tails. Uh oh... a super light, super stiff ski. It brought back memories of trying the Blizzard ZeroG 95 in dense chunky snow, which I thought were a bit unfriendly, though great on hard pack. On snow, I was thrilled to find the Alp Tracks to be surprisingly friendly, eager to turn but predictable, moderate flexing, and fun! They have a happy flex, not harsh, not wimpy, and not terribly stiff either. They make a really good pairing with the Alien RS boots. The tips have some early taper and a good amount of rocker, similar to the DPS Wailer 112, but less pronounced, and the Alp Tracks have a much more present tail (yet still easy to release) than my old and beloved Wailer pure carbon 112s and 99s whose biggest fault I think is their tail-less feel on steeps. This combo helped the Alp Tracks not deflect as much through the soft but heavy crud and avi debris that basically covered the upper areas of Mammoth Mountain while I was testing these skis. In fact, they did shockingly well in these conditions, and not just for a lightweight ski. They also were great on steep chalky stuff, and not bad at all on some bulletproof panels that started showing through under the new snow. The behavior and feedback from the Alp Tracks on hard pack was much better in my opinion than what I've experienced with the DPS Tour1 skis I've demoed a few times (which I feel are great skis but a bit harsh on firm), and better even than my pure carbons, but not quite as good as the Alchemist build (which is in a very different weight class of course). These skis aren't meant for hard pack obviously, but its nice to find out they can handle it well enough. I can't speak to durability yet, but these are by far my favorite lightweight skis I've tried in terms of downhill feel. If you're on the fence on size, I'd say go up. They turn easily, and swing weight is practically non-existent. I can't wait to get them into some real powder in the middle of nowhere.
