Buy enough rope. Adding slings and carabiners introduces points of failure. Anchoring high in the tree increases leverage. A clove hitch isn't the best top rope anchor.
This is the anchor for Ronnie's Leap. Orange paint usually means cutting down the tree, or did they mean just cut one dead limb? The tree is fine and losing it would greatly complicate anchors on these popular climbs.
Get a real anchor, webbing way up on the trees is sketchy and hard on the trees.
One piece of webbing and the climbing rope is dragging over the top of the cliff.
