I have arrived late for the Whoopie Sling party, so I am learning... I got some tech line from Scott at DIYSupply yesterday. (Great vendor!) I made myself an adjustable structural ridge line that I hope to try out over the weekend. I was looking at videos showing tarp ridge lines and was wondering if anyone has tried threading a few inches of whatever brand of hollow core line you use for a tarp suspension onto your ridge line with a loop (locked Brummel?) hanging off the end toward the tree for attachment instead of a Prusik knot? Has anyone tried it? Seems like it would work for centering the tarp as well. I'm sure someone has at least tried this, and it may be common. I am just having a hard time seeing illustrations with that option. Thanks.
