Already been using it- for years!
Anyway, problem solved. I took my tarp down and things were back to normal. The ropes of the hammock and tarp were some how rubbing, apparently. Probably because of some weirdness when I hook up to the 2x4 crossbeams that I have between the trees and hammock, with the tarp cords going over this and to the trees.
Using a normal hang from trees only at Neo's fall get together, all was quiet.
