sorry warbonnet my man, i'm still not convinced. with the 2nd inside patch, the thread stitching the patches together, with the silnylon sandwiched in between, are going to be pulled toward the outside, there fore pulling against the inside patch which is last in the line of pull.
besides, in my use w/ these pull outs for over two years now, i have rarely seen them take nearly as much force as the corner tie-outs.
i often tie them to near by branches. that allows a lot of flexibility too. ...tim
