If you want it to stay put without glue...bend a crook in the end of the wire. I have made my version of that head for years with great holding success. I make them for a guy that uses the Berkley Gulp Leeches and he was having the same problem. With a barb the bodies would split like a stick of stove wood. But with the wire and the custom bend...it stays put and with ALOT less damage to the bodies. AND THE WALLEYES LOVE THEM!!!!!!!
