Anything pinching the whoopies is bad news. If your using the whoopie to "tie" the triglides and attach the treehuggers by adjusting the tree hugger on the triglides, it does work. I'm guessing that's what you mean.
For me, it's too many moving parts with the whoopies adjusting and the triglides/treehugger adjusting and xtra securing of each line to ensure no slipping. I like it simple with less.
