Well, if throwing my zero degree bag over me last time kept me comfortable enough to sleep, but only if I didn't move, I just can't imagine that a liner or thin wool blanket will do crap in comparison. I have to keep perspective before I run off and but more stuff.
On another note, I have plastic tent stakes and I hate them. I also have the thin steel ones that come with tents and those are just as bad. Steel triangle shaped, or twisted aluminum ones any better? I can pretty easily bend the aluminum ones in my hands, so I feel like those might be more fancy visual marketing than anything.
