Greetings!
Smalljaw is right. I have used thousands of Worth swivels with a standard wire #2
split ring with out problems. Although the last time i purchased them 200 out of 1000 did not turn. Quite a problem as lures were packaged when i discovered it.
I may be able to help you with lighter wires.Nitinol wires need a crimp sleeve to hold
the swivel. Also some injected 8 inch grubs.
