I had this question going in the Warbonnet forum, but this seems like the more appropriate place for it...
I've decided to use Kelty Triptease for my tie out and guyline cord. However, I was curious how long these should be.
I was planning on using 10' tie outs on each side of the tarp. I was going to tie to the D ring of the hammock, loop around the tree, and come back tightening the line with a figure 9.
For my guylines I was going to use 5' of cord connecting to my MSR groundhogs using the trick Brandon uses in his videos.
