Whoa! What are ya talkin’ about. Using 2 ridgelines to give yourself more options. It’s tricky but you’ll need to practice!
My first attempt at double ridgelines was a really good try, I learned a few things and before I left that day I went back to a “Diamond A Frame”. The “”Diamond A Frame” is great for photos, isn’t it? haha
Get yourself a cheap tarp and give it a try! Learn some knots, learn to toggle, add to your skills!
