Well then not to put too fine a point on things but I suspect that you could have done better site selection, Jeff. There aren't many places on Earth where you'd be hiking on a flat featureless bedrock plain that didn't have a better site within 10 minutes walking distance. I mean, really, you couldn't find a couple of large rocks to tie off to? Got a picture of your camp site by any chance? (It does sound neat.)
All I'm saying is that this meme about it being difficult to find tie-out points for NFS shelters is the equivalent of urban myth. OTOH if you are someone who just wants to throw up a FS shelter when you're worn out at the end of a day of hiking and you're willing to carry the extra weight, go for it. HYOH. No one is saying that you are doing it "wrong" by using a FS tent. We're just saying that all the worry about finding tie-outs for NFS tents is much ado about nothing.
Clearly, yes, there are special cases- like mountaineering or wallhanging or camping on chickees in the Everglades- that require special equipment. And if you have managed to find that flat featureless bedrock plain that I mentioned, well, all the more power to you. If nothing else it does sound interesting and would also qualify as such a special case, but IMO still doesn't justify carrying a heavier shelter the other 99% of the time. Because I don't think that the OP was asking about niche uses- I suspect he was asking about general use in which case I stand by my statement that NFS shelters are perfectly viable, simpler, and lighter- if not as bombproof in most cases. Even in 99% of desert or canyon hiking there is no issue driving stakes or finding tie-outs. Hiker's peccadilloes differ so they aren't for everyone, but they are nonetheless great shelters.
I'm decidedly not one of the tarp-fascists, but I'm also not ossified in my thinking nor falling for the FS tent propaganda put out by mainstream manufacturers. I've compromised between lightweight/comfort/bombproofness by carrying 'mids most of the time. I use a bivy to address bugs when they are an issue. Every so often I use a poncho tarp when I'm in a fanatical mood. At the other end of the scale, sometimes I use a cheap metric-ton Coleman FS tent when car camping with the family. (And, yes, those people who complained of FS tents getting blown into the next state by the wind were talking about when it is unoccupied, which my Coleman has tried to do on occasion. And it takes a LOT less than 40mph, brother.) But for general use? A NFS 'mid.
I don't think that FS tents will ever be quite as light as NFS tents. After all a FS tent will always need at least two poles. They are, however, getting close enough in weight that the difference is probably not terribly significant for most users. But the people here aren't most users, and I am forced to presume that there is a reason the OP asked his question on BackpackingLIGHT, after all. A lot of people come here because they have heard of the tarp or NFS thing, are intrigued by it, but need a little reassurance about it before they try it.
PS- Troll comment rescinded. Good to hear from you again, Jeff.
