Mick,
They're all bug prof; you need to select by your size & use. Go to
http://www.hennessyhammock.com/ and select first for your size. Then look at use. Go to the "Model Comparison Chart" first.
The real light weight ones are meant for guys climbing mountains, and are probably not a good one for you. The Expedition Asymmetrical is the "standard" Hennessy. Unless you are too large for it, that would be a good one.
The Explorer Deluxe is for taller, larger fellows. The Safari Deluxe is for really taller, larger fellows. I'd expect that either the Expedition (what I have) or Explorer would do you fine. In either case, I recommend you opt for the hex rain fly.
I have a Scout for Katie, and she - at about 4' tall - has plenty of room in it.
HINT: Click on the "Australian Orders" button along the left side. You may be able to go see some locally. Also, he often runs specials on "seconds". I bought one for Katie and spent 20 minutes looking for the flaw after I read right where it is. Cosmetic flaw only, and not much at that.
Read through all the bullets along the left side; you'll learn a lot.
Plan on using a closed cell foam pad under your sleeping bag. It will insulate you well. I use a Ridge Rest because it folds up so nice. I started with two, 3/4 length pads, taped them together side by side with a 1" gap in between for easy folding. I then trimmed them narrow at head & feet, wide at shoulders. Scraps I re-taped together for a doormat under the opening of the hammock. Gives me something to step on getting in & out.
This pad has many other uses. Kneel on it when loading & unloading up under the decks of a kayak or decked canoe. sit or lay on it in camp, up against a tree or log. Kneel on it while cooking or washing up. Lay it in the bottom of your boat for a kneeling pad while paddling rough water.
And, welcome to the most comfortable nights sleep you'll ever have.
