Prussics solve this problem because you can slide a prussic knot along the entire length of the ridgeline.
All I am saying is replace the Prussics with this idea. Leave the knot bone, figure 9 or whatever to make the gross adjustments, then use this constrictor idea in place of just that Prussic. It stays in the middle closer to the tarp itself. I hope the illustration helps. Thanks for looking ya'll.
