What kind of cord is your tarp ridgeline?

[OregonJim]

I used straight 550 paracord initially, but had problems with stretch. Then I had a not-well-thought-out idea to add a section of shock cord in the middle. While that kept the ridgeline taut as the paracord stretched, it did nothing to keep the tarp from sagging - because each end of the tarp was still connected to the (stretching) paracord. Duh. So I replaced the whole thing with yellow zing-it. No stretch and much lighter.
