Oi, a moribund week here.
The skis listed were the most diverse list I could slap together of skis I could either weigh myself (either own, or a nice local shop let me bring in my scale), or were owned by an acquaintance whose numbers I trusted. There's enough fuzzy math in this area that I was unwilling to compromise. Ergo the bias in selection was unavoidable.
Ross, regarding the superiority of free heel gear for rolling terrain: I could not agree more. I am also hard pressed to think of many instances in which a leather or pleather boot wouldn't be the best choice for such routes, again with the possible exception of the Excursion (which doesn't fit me, so I've never used it). I hope the boots get better.
With regard to metal edges, it would be interesting to take apart a ski and see how much weight they add. My suspicion is less than one might think. In any case, some folks can get away without them. Most folks, with only one or two pairs of skis for true backcountry skiing, will be best served with edges.
Paul, your citation of Asnes skis brings up an interesting point. I'm a big fan of skis the shape Skurka used (the Sondre), namely a tip right around 70mm and a waist around 55. Just skinny enough to fit in most set tracks, and wide enough to have skinny-ski style float in powder. The tricky thing is that there is a huge variation is flex and camber amongst skis this size. Some, like the old Outbound Crown or the Fischer E99, are quite stiff and have double camber or close to it. Others, like the Glittertind, are soft and have camber and a half. The later are much, much easier to turn. And while double camber is nice in set tracks or when skiing on hard surfaces (the Outbounds skate great on frozen lakes), I'm not at all sure that this adds much to forward speed in unbroken snow. This kind of ski, pins and a good boot is a touring quiver of one, but buyers should be aware of the more subtle differences and buy accordingly.
I also think the Asnes "skin lock" is a solution searching for a problem.
