Well worth it and Dutch always gives first class service IME. Nice guy too.
I've used it all over the years it's been out. Tarp Flyz, Dutch hooks and Dutch buckles sit on one set of suspensions and lines, Whoopie hooks and looped end tree straps on another rig.
Whoopie hooks and looped tree straps are the simplest, cheapest and lightest way of blinging and cope with any tree size.
Dutch hooks and dutch buckles with whoopie slings are the most adjustable and often the quickest for the hammock.
