I appreciate everyone's input. I certainly see the benefit of a free standing tent, and I also love the Shangri-La tents. Another major concern of mine is pack size. We've got some fairly bulky sleeping bags, and as a compromise with my wife for even being allowed to take him camping which means that we bring along too many clothes, in case he gets wet. Can anyone comment on the comparative packed sizes of these tents? I had thought that by using our trekking poles, it would save space over a tent that required separate poles. I've got a bunch of old, heavy gear, and I'm taking inspiration from this forum to lighten it up a piece at a time.
Our longest hike together so far has been 6 miles, but with everything strapped to the outside of my external frame pack, it's a bulky way to hike.
