Yes, the TT is a great product line, and Henry is heck of a good guy to deal with as well.
hutch762mg (now that I type that out, NOW I get it), I think that in several respects, a tarp is MORE versatile than a tent. More than once I have had bushes or small trees inside the tarp with me, sites that would have required extensive (and sometimes illegal) landscaping in order to work with a tent.
The tarp can be set up high or low, and wide or narrow. I've squeezed the tarp into some tiny sites before. If you can find a place *just* big enough for your sleeping bag, you can tarp it.
If I don't have the bug hut with me, I always carry a headnet with me as a backup. I've been snow camping in the late spring and SWARMED by random little gnats. That being said, I find that sleeping in a headnet is an unexpectedly stuffy and uncomfortable experience, even wearing a hat to keep the net off my face.
