You might want to try just a mini "s" biner from the two prussiks to the tarp itself. You don't really need the ability to tighten them much, and the biners seem a lot easier than figure 9's there. Just a thought. Also, maybe replace the fixed tree end with a knot bone for similar reasons. I copied my set up from whoopieslings.com continuous ridgeline and it works great.
