On a serious note with two in a hammock, it is surprisingly comfy. I think the key is the weight of the two people should be a little close. If both people are close to the same weight then the balance isn't thrown off. You were also right about shifting so that your hips aren't side by side. That spread out the weight, and made it feel like two hammocks. So if anyone is wondering, it would be doable for an overnight or weekend campout to save weight or money on gear. The only problem would be if you move a lot in your sleep. I think both of us almost fell asleep laying there, so that was proof enough for me.
I heard that Skinny Badger didn't even need the Walmart blue pad Shadowmoss offered, or the SPE that he was offered. He had two pads of his own, so he must have done pretty good. I enjoyed talking to him, a real nice guy. Hope he gets active in the forums.
