I have seen repel rings be useful to hang a structural ridgeline. Also oppies company who makes whoopie sling suspension system uses rapel rings in his all in one system. They are not that bad.
Oh if you are going to make a tarp ridgeline you want to make it continuous they make me happy.
Bacon and Camping makes me happy.
