best of both worlds
For the summer, the bottom entry is great. It's a fast way to get away from the bugs but it can be a little scratchy on the legs and other gear.
For cool weather I love my 2QZQ zipper mod. If the bugs aren't bad I can flip the netting back out of my way and look at the stars or reach out to adjust my quilt. I can sit sideways in the hammock like a big comfortable chair while I put on my boots in the morning. That is just so, SOOOOoooo much better than crawling out of my tiny tent and crouching in the doorway.
In the grand scheme of things I might have been as well off to just buy another hammock rather than mod my HH. Now it's an all-season all-weather model and I love it.
