I’ve pitched a Hex 3 between 2 trees with accessory cord, 1 mini-biner, and a clove hitch. Its a little tricky to tension the canopy as you have to continuously adjust the clove hitch so the tension is parallel to the ground. The other problem is lightweight accessory cord isn’t static (it has some stretch to it) and I found myself getting up in the middle of the night to re-tension the single “guyline”. It takes an incredible amount of tension to get the Hex 3 perfectly taut using this method.
If I were to do it again this is what I’d change.
1. Get a slightly heavier cord with better static properties. Perhaps the heaviest ultralight dyneema would work good.
2. Abandon the clove hitch in the middle for a short prussik (2 wrap) around the static line which slides freely with no tension but cinchs tight AND dead center on its own when the line is tensioned. Keep the mini-biner (although I’m sure you could tension with over 300 lbs of force using this method).
3. Carry 2 ultralight long slings (120 cm, Onsight makes them out of dyneema and sells them @ MEC), and 2 wiregate biners. This will allow you to pitch the tarp like a Hennessy hammock, easily adjust the height of the pitch points, save the trees, and re-direct the tension to the ground (maybe 2 beefy Y stakes). Learn how to tie a bowline on a bight and you have 2 bomber loops for 2 Y stakes per side. This arrangement should be sufficient for most ground types you encounter.
The big bonus of this system is that you have a clothsline for drying your bags and insulation in the morning (even your Hex 3 to rid of condensation).
Good system, just needs the bugs worked out so its more user friendly.
Can’t say anything about the bugnet though, I would just invest $15 and get a headnet @ MEC. I can’t see insect pressure inside the HEX getting THAT bad!
