Welcome to HF from NC!
You know I'm a bit jealous that you live so close to one of the best hammocking/hiking areas in the world... I'll be thinking about that as I drive the 2.5 - 4 hours needed for me.
You may want to consider a tarp that will pitch about one foot longer (on each end) than your structural ridgeline.
Some just buy a entry-level tarp at first with plans to pick-up a more feature-rich (and costly) one in the future.
