In summary: Aside from a bivy sack for good weather and race pace endeavors, I've sold off the rest of my shelters. It's a great cross of a pyramid and a tarp.
Finished weight, seam sealed and with 40' of the included guy line is 19 oz.
Construction is excellent. No issues there.
The design is great and very adaptable. The pitch can be higher, rommier, and more airy, or low and quite windproof. It can be easily pitched with trekking poles, paddles, or (because of the gridstop peak reinforcement) a handy branch. During bad weather I guy up the midpoint of one of the panels as a door, and do so quite close to a thick tree. With this arrangment and the rest of the edges flush with the ground I've enjoyed snug nights of sleep during 30 mph winds, rain, snow, and combinations of all three.
Even pitched to the ground as per above, there is plenty of room for two 6' guys and all their gear. With an angled pole or a rope suspension, three would fit without problem.
The linelocs are very nice. The weight and complexity are more than made up for by the ease of use they afford.
7.2010 adden.: I continue to be impressed by this shelter. Provided that it is solidly staked out, it will stand up to some serious wind. Not only stand up, but hold steady with remarkably little flap or movement. It makes for a very restful night of sleep during bad weather.
12.2010 adden.: I finally found the limit of the TS w/r/t wind. Not in the design, nor the fabric or tieout strength, but in the quality of the anchors. I camped on a rock beaches in Glacier NP, with plenty of fetch off the lake to get 60+ mph gusts. Once I got all the tie outs set and equalized the shelter held fine, but until then some of the anchors would get uprooted under strong gusts. Conclusion: get the anchors solid and this thing can take serious (60+ mph) wind.
