I grab the adjuster with my left hand and pull it up under my armpit or throw the rifle over my right should and pull the slider across the chest. I have made them the more common way with the slider going toward the front with a plastic loop in the middle of the sling but then you have less adjustme t range and the sling does not tighten down along the gun for storage.

As far as rot goes, I was basing that off what the webbing company recommends based on the usage you plan to do. I had polyester webbing that was not tubed and the sides where rough and the webbing was very thin. The tube style is soft and remains flat.
