Barry, I have a swiss gear that looks just like the second link you posted, however, mine has an aluminum pole. I have only slept in it a few times, once in South Texas, and a few times in the Rockies. I have never been in it in a heavy rain, although I did set it up in a heavy rain (in the backyard) with towels on the floor to see how much it leaks. I have found that it is terribly ventilated especially in Texas, if you close it off completely. If you open it up, then no condensation (even with me and my 2 sons inside all night), in which case it becomes a very heavy tarp tent that is less waterproof. So, to sum it up, I basically agree completely with Barry.

" Buy a heavy tent now, and you’ll always be longing for a much lighter tent. And thus I love my 2-man GG Squall Classic (25oz).

That said, to encourage backpacking--- It’s probably OK for a few hiking trips with nice weather with a Swiss Gear tent."
