My gf and I are going to be thru hiking this summer (SOBO) and so I'm looking for a shelter for two. I've been looking at the Tarpten Double Rainbow and the GoLite Shangri-La 2 w/ Nest. They're both comparable in weight, dimensions, and at the moment price. I love doing research so I'm having a tough time deciding between the two and would love to hear some feedback. I've seen positive comments about the Double Rainbow, but it doesn't seem like the Shangri-La is used as much, but I'm not sure why.

We're hiking together, but I could forsee less than ideal scenarios in which we may need to be separated for a day or two. If that's the case, the Shangri-La would be nice as one person could take the nest and the other could take the tarp. So, what do you all think?
