Made a sew-up PLUQ today, and now I'm playing with the suspension.
Initially I made some triangle thingies out of braided mason line, and fiddled with getting the dimensions of the triangle right.
After a couple of refinements, I'm now at this - a loop of mason line, attached to the ridgeline with a prussic/klemheist knot. Both pieces of shockcord come through and are held by a single cord lock.
Benefits over a triangle thingie are that this is adjustable along the ridgeline, and eliminates a cord lock.
Planning to hang in the basement tonight & test it out.
