Dan, where did the spin pole bridal line break, at the bow (chafe?) or at the tip of the pole? And did the line actually break or did a knot come undone at one end or the other?

I've been worried about chafe at the bow, my bridals pass through a hole in the bow, with a stopper knot on the backside. I've been thinking of using some plastic tubing to prevent chafe there, is that your setup?
