What about safety wire with a twist or two, heat shrink over that to make it a bit more smoother? It could be removed and no damage from the glue.
Safety wire might be a good option too. The hot glue is easy to remove, put a little alcohol on it wait a bit and peel it off. Will never know it's been there. As far as the braided fishing line and CA I was only going to glue the end of the fishing line.
