I think a lot of people who mold baits tend to use screw eyes, which probably hold perfectly fine. I still wanted to through wire my molded lures so I make a simple jig for each plug and use Paul's bender to make a harness that fits the mold every time. I also like the thinner diameter of the stainless wire over the thick screw eyes for use when tying direct or a clip. Much like turning on the lathe, everything in molding baits is done in steps.
