I think you should consider a hammock. I don't camp a lot, but I spent about 7 nights in one this past year. I am much more comfortable in a hammock. They are much more versatile than a tent as to where you can can set them up. When you boil it down I don't think there would be much of a weight savings though. If it is cool or colder you will need an underquilt and that adds to the weight. The biggest disadvantage to a hammock is the susceptibility to the cold. Otherwise they're great. I have a Warbonnet Blackbird.
