I agree, that if the ridgeline is always at its maximum tension, height and angle don't matter much, but if you raise the suspension angle, you can get the ridgeline loose. The purpose of a ridgeline for me is not to set the maximum tension. In fact, I have never had the ridgeline tight enough to matter. I use it as a guide. If I can easily bend the ridgeline, it is plenty tight. I don't think it should be at the max tension. It also keeps the bugnet off my face.

Changing the height of the straps changes the tension, but in theory, the lay of the hammock is insensitive to that in the range of heights where the ridgeline is taut.
If the ridgeline cord does not stretch, this explanation makes sense to me.
So I'm interested in the several responses whose experience is that strap height and ridgeline tension matters. In theory, practice and theory agree but in practice they don't?
In my own experience in a Blackbird, I need to scoot my body around to deal with the tension down the center of the hammock. No matter what hammock I'm in, I move around a lot at night and with each move am positioning to accomodate that ridge.
