a couple of weeks ago I had this not so bright idea to try adding a dab of white glue to the knot between the leader and the tippet. I thought it might seal the knot and make it a little stronger. Well apparently there was some "bad chemistry between the line and the glue" as when I tried out the rig a few days later the line broke at the knot with the first fish. Any ideas as to why the glue would weaken the line?
