A marlin spike and toggle in the strap.
The woopie goes over the marlin spike knot, not the toggle, down to the biner. Shug has a video on this that is very easy to understand that is on you tube.
Also if cutting down the distance between trees is what your looking for ,you could larks head some buckles to your hammock cutting out the woopies all together. Then you could pull the hammock suspension in pretty close to the trees.
