String Loops or Metal Rings?

[LoneWolf]

Yes, I have a double knock point set up. One the arrow rests on top of, the second underneath a little wider than my release is. This holds the release from sliding. My Wynn's is the style that is a flip lever . When the string goes into it, a lever flips closed perpendicular to the string. I have shot this set up on three different bows, all with the same release.
