I like it....especially the ridge line. Like using Dutch Stingers without the Stingerz))))) I had DutchFlyz but they were just to small for me to see to move on the line without my glasses. So I have been using Stingerz. Like 'em.
I tie a similar knot when I use just line and no hardware but loop on the line near the tree.....not coming back all the way to the tarp.
Nice to see your rig.
