Ooh, I'm curious. Saying that because I recently put some of Dutch's plastic quilt hooks onto zing-it continuous loops, which I then prusik'd onto my panel pullout guy lines. They let me attach the long red guy lines around trees (wrap around and hook back onto line, or around an object and hook to opposite prusik), and I can also hook them onto the corner guy-lines for porch mode.
I said I'm curious b/c afterwards I thought that perhaps small (size #0) s-biner or even mitten hooks might be nice since they would prevent tangle issues, but you mentioned that you don't need to worry about snagging your lines so what are the design differences? Have a close-up pic?
Here's my setup for reference:
Side panel pullout lines in action (each red line is looped & hooked around a large downed branch out of frame):
Hooked to corner shock cord loop a la porch mode:
