The second one, by far, has my vote. But I do it kinda' backwards. First, it is just a bolt, no need to place a special order. Second, I treat it as non-adjustable and don't use a hole in the middle, but wrap the cable wire around the bolt a turn or 2 and use a jamb nut to clamp the bolt solid to the pivoting bracket part. The wire wrap then pivots around the bolt. 2000hrs seems to indicate this works pretty well.
