I was considering this set-up for a ENO hammock. Seeing as I do not own the hammock I thought I'd post it here and see what you guys think.
My set-up would be the ENO Slap Straps around a tree. The actual hammock on one of the furthest loops. And a ridgeline tied to one of the loops closest to the tree with a Quick Release Knot. And the tarp would be attached to the ridgeline with a Prusik Knot.
In theory this would work. But I don't know if it would be practical in the field.
