I loved that setup on the wildcat.
Karl, another thing to try is to untie the line from the top of the ring and tie it with a figure eight and loop style around the top of shackle and bottom of the ring, provided you have a one piece welded shackle and ring. The line should run in front of the top of the ring.
We had no issues for a year then they started so we switched to this method and had no issues since.
