Good article, once I got by the title. (That was a bit of sensationalism, I guess.)
Anyway, I see this as pointing up the problems between "pigeon holed" categorizations we are saddled with. A two or three pound tent is not that much of a difference from what was in use 10 or 20 years ago. To call these tents "Ultra Light" is a bit of a misnomer.
To me, these are mostly tripping tents I would not use for long disance hikes. For a few nights out with the wife, sure. For a week of straight up hiking? Nope.
One big reason where I see them missing the mark: Complexity. There are a large number of poles certain to confuse me in the dark after a hard day of hiking. The clips, swivles, knuckles, Y-joints, pull strap tensioners, buckles, loops... well, the list goes on. A good Cooking Vestibule? Time to set-up all the gadgetry up? Time to tension all the straps? And so on. Not that this is difficult, it is taxing on my 60+ year old back, sore after hiking for 10 days (looking at at least 3 more before I can get to a resupply,) and tired (getting cold) after a 17 mile hike through drizzly ADK mist.
Sean did a great job describing the tents. I know these tents are not for me and I need not look anymore. THIS is what makes a great review. The fact that I can STOP looking. To me, this is as important to me as looking at what CAN fit my needs.
