I have an REI two person and it is a perfect backpacking tent. I have found most two person models made today have cut weight by meshing the top portion of the tent for 2-3 season use which does give good visibility but also includes a rain fly for heavy downpours.

Every time I put a tent down, I dig a trench around it to draw water.

I recently purchased an Eagle Nest Outfitters hammock and while it served me well on a weekend trip, hammocks need to have a place to put them up and honestly its hard to find, at least in the desert SW. I take it to the beach, to national parks, etc to sting up in the family BBQ areas and its usually hard to find lash points.

I am determined to continue using my hammock as often as possible but a light weight tent is IMHO the best option for long term travel. Its just to versatile for all the reasons listed for the weight it is.
