I think BPL has covered some high performance ski gear, but not a lot. Generally speaking, there just isn't that much coverage of winter gear. For example, a lot of people will never learn how to ski -- so maybe a "snowshoe state of the market" would be in order? But I've never seen it (or if I have, it is been a long time since I've seen it). The same could be said for climbing, which in many ways is much closer to BPL's mission (the whole ultralight concept was pioneered by a climber after all). But again, I haven't seen that much. On the other hand, there is a decent amount of coverage for Tenkara, which is a subset of fishing that a lot of fisherman I know refuse to even consider. This is really good, and I think a lot of people enjoyed that article. But BPL doesn't have experts in every outdoor sport, it just happens to have lots of people that like to fish.
One of the tough things about covering winter sports is that it is so complicated. You basically have snowshoeing, snowboarding (with or without a splitboard), and two types of skiing. Without a doubt, the fastest, lightest stuff is Randonee. But that isn't necessarily what all of the great mountaineers are using. My guess is that most of them use A. T. gear, but I've seen plenty of ambitious mountaineering (which make the quick ascent of Rainier via Paradise look like a walk in the park) done with all three types of gear (snowboard, A. T. and telemark).
I agree that a lot can be learned by the racers (who drive a lot of the innovation, to be sure) but I think there is a natural limit to it. The boots and bindings are simply superior to tele (even telemark skiers will tell you that) but the skis are a different matter. Most of the racing skis I've seen are fairly skinny (by modern powder skiing standards). I could be wrong, but my guess is that there aren't many racing skis (if any) that are really fat and have a lot of rocker. This means they are great for consolidated (or relatively consolidated) snow, but not so great for deep powder, or even worse, for Cascade slop (which has a very high moisture content -- great for making a snowball, terrible for skiing). If they had races where each skier was expected to ski their own line of fresh, deep snow, then I'm sure we would see more really light, fat skis. Of course, such a race would be very difficult, if not impossible to organize. Again, I could be wrong about this -- and if so, please correct me.
As I mentioned, though, the racers simply aren't interested in waxless skis. It doesn't make sense for them. They will skate or put on skins. But in a lot of terrain, waxless skis just make life more enjoyable. Skating can be a real pain in deep snow (especially if you are on a slight incline). You may be really fast putting on or taking off your skins, but I spend more than 10 seconds just putting the mesh onto the skin after taking them off the skis. I can get faster, but it still isn't going to be fun. Skins are no big deal if I am skiing up from Paradise to say, Camp Muir (I wouldn't take waxless in that case) but if I'm touring around nearby Mazama Ridge, with its dozens of little dips and bumps, it is really nice not to have to bother with skins through most of the trip.
Speaking of which, the video is really impressive, but it is too bad it got cut off before he actually put the skins away. I've known about the fast removal of the skins, but not the fast storage. I would like to see that part (especially the application of the mesh). Also, I would really like to see the quick application of the skins. I can remove them without taking off my skis, but putting them is another story. It is always fun to see guys doing things much, much faster than me.
