Cool idea. I always just bought weedless jig heads, too, either with monofilament fibers or 1-2 wire strands. It's a good idea to just get some craft wire and make them yourself. Thanks for including the suggestions for what gauge wire to get.
I just bought a Stan Sloan jig at Bass Pro the other day because I noticed that it uses two wires that do not run directly to the hook point, but rather splay out at a few degrees from the hook point on either side. I thought this design looked a little more weedless because it would deflect a potential snag away from the hook point sooner, or allow the wire to flex a little and still be effective as a weed guard. I think it would be pretty easy to make this modification, but not sure what the net effect would be.
Does anyone have any data on the catch rates comparing 1) unguarded hooks, 2) fiber weed guards, and 3) Texas-rigged style (where the hook tip is hidden inside the plastic body)? Does weedless rigging effect bite and catch rates?
