While I wait for a BDWD tarp, I have to augment my GG 10 x 10 with a 9 X 9 Kelty for bad weather. The 10 x 10 just doesn't cover the Switchback enough for my liking. I made two more prussiks with toggles and added to the line. Is this too much stress on Opie's wonderful tarp ridgeline? Do I need to make another and just string them off the same trees? See very bad drawing below.
