yep. If a structural ridgeline is 'guitar string' tight then it's too tight- see shugs videos. Should be able to twist about 90* when unloaded and about 45* while in the hammock - if i remember correctly (pushing up on it with your thumb while pushing down with RL gripped in your fist).
"Climb the mountains and get their good tidings.
Nature's peace will flow into you as sunshine flows into trees.
The winds will blow their own freshness into you, and the storms their energy,
while cares will drop away from you like the leaves of Autumn."
— John Muir
