I'm totally new to hammocks and have bought new gear for an upcoming section hike of the Ouachita Trail. I bought a Thunderfly Tarp and would appreciate advise on guyline lengths and rigging for the doors. I've looked at lots of photos: many are guying the doors to a tree if close enough, but sometimes I see that the guyine has to be staked to the ground if the tree is farther away. Please let me know what works for you (length, type of cordage, and any specific hardware or knots). Many thanks in advance.
