Okay folks, a liitle more info. I went back outside this morning for the purpose of taking it down, but ended up playing around with it some more. I found out that:
1: the hammock is more comfortable unzipped. All of those problems (minor) with my feet go way.
2:Also at this time I discovered a position on my left side with legs straight which was doable. Maybe not the very best, but I could sleep that way at least for a while. After I found this sweet spot, I was also able to achieve it with the hammock zipped up. By the way, this sweet spot for me (6'1") was with less diagonal, laying closer to the zipper. So I was not quite "straight", but was definitely less diagonal than I am laying on my back. That's something now I will have to try with my ultralight Explorer. And maybe other hammocks also.
3: I attached my Warbonnet Climashield torso UQ. After a little fiddling with suspension tightness, it works really great. On my back it was warm and snuggly right off the bat. But when I turned on my right side, a huge gap developed underneath. So I got out and tightened it up a good bit. Now everything seems snug in every position, but it really felt too tight. And when on my side, it felt like there wasn't enough room. So I slightly loosened it, and now all was good. I was warm on my back, left side and right side. Though really, for me sleeping on my side I think I would appreciate one or 2 inches more width in the UQ. But, it got the job done. And I am able to get the net out of the way enough to make needed adjustments, though it would be even better if I could get the net completely out of the way.
