I''ve been using this knot for my braid to leader knot for years, with no issues.
Last time out I had TWO of them come undone while playing fish.
What am I doing wrong? (I've just noticed BobF suggests putting a spot of glue on it too, which I hadn't noticed before, but it would assume he's also had this happen for him to recommend a drop of glue).
Does anyone have any suggestions, because one of those I lost was a nice fish!
