Putting a twist in a strap does weaken it.
Try pulling a sheet of at apart from the middle, you won’t do it, pull it apart from the edge and you will. A 2m strap with a twist is 2m at the middle, both outer edges are slightly more due to the half a circle it’s covered too, do you end up with high tension on the outsides and a lower 1 in the middle, that not how they’re designed to work, DCPC dude is right
