I have an ENO double nest and it has no ridgeline. What is the purpose of the RL on the traveler? On my blackbird, I can tell that the RL needs a fair amount of sag or else it gets too much of a ridge under my calves. If I start hooking things to the RL or the suspension of the hammock at all, it increases the tension and makes the ridge. So I'm not sure if I like an attached RL on a simple hammock. What's the deal?
