I use a figure-9 on my single tarp ridgeline with my spinn tarp and I get sag every time. I just figured it was due to slippage since the 1.75 line is really too small for the small figure-9. Are other people using a figure-9 and the 1.75? (Nite Ize recommends 2.0 mm line or larger.) And if so, how do you keep it from slipping?
"Do what you can, with what you have, where you are."-Theodore Roosevelt
I tried several wraps around the teeth of the 9, bring it back around and over the 9, back over the line....
You can get it to lock up, but at that point you might as well have tied a knot with the time and effort involved.
The road goes ever on and on Down from the door where it began. Now far ahead the Road has gone, And I must follow, if I can, Pursuing it with weary feet, Until it joins some larger way, Where many paths and errands meet. And whither then? I cannot say.
