Clearly you haven't laid in one yet.. maybe get one ordered up and decide for yourselves?... I spent the night in it and being a chilly night I used the overcover, lows in the upper 20s and no condensation at all with zipped up completely.
Only thing I'm not sure about is the tie out placement. unless I pull them to opposite extremes, out and almost parallel to the hammock I get a little floppy section between the 2 attachment points. note this is just in my shop and I staked out with my hammer on one side and a pet carrier on the other, it might not be an issue with more room to maneuver outside.
