Here is a quick shot using a Dutch Hook (the Ti kind) to connect a tarp to the ridge-line. I use 6" pieces of zing it to connect the hooks to the CRL in a 3 wrap prusik.

It makes the tarp easy to get on and off the ridge. I initially thought about using a gated biner or something like that to connect it. But these weigh 0.6 grams each. My 25' zing it ridge-line with a dutch hook and flyz system for connection to the trees and two of these hooks on the line for the tarp come in at 16 grams total which is about 0.56 ounces for the metricaly impaired.
