Just received my first pair of Dutch Clips and gave them a try yesterday. The diagram that came with them suggested positioning the clip to the side of the tree, so the strap comes through tangential to the outer edge. It seemed nearly impossible to get the clip to stay in this position, though. When I'd tug on the end to tighten it up, or when I'd load up the hammock, the loop would swivel around the tree and the clip would wind up more or less centered again.

Any tips to get it to stay put? Is the force on the strap/tree/clip significantly different in either orientation? Do I even need to worry about this?
