Oh man, I wished I knew this earlier about the tag ends needing to be kept for retightening. I cut mine off almost flush and thought later in the day that the pretied knot wes slip and sliding and not reeling back into the reel when it was passing the tip of the rod. It kept making my 3ft adjustment auto reset to about 1ft each time I reeled in.

I think I have some mono 15# test or 30# so will try tying a stopper with those for a thicker stopper knot for the bead.

Speaking of beads, any homemade ideas for bead alternatives?
