It all depends on how you hang your hammock. In order to keep a non-structural ridgeline taut, you'll have to hang the hammock exactly the same each time.
Having a structural ridgeline is SOOO much easier, and makes for a consistent hang.
I have attached ridgelines 2 ways: When using the WBBB method of whipping, I've put a loop through the bundle with a triple-overhand-knot at the end.
I've also just tied a bowline to the larksehead on the suspension, and used an adjustable taut-line-hitch on the other end...
