I made my grandson some jigs once and he was out back of the house (in Jax, Fla) and latched into a big one. I don't recall seeing any rolling on top of the water. He wound up loosing it when he got too excited but it sure was worth it just watching him. Anyway I don't know if a jig will work all the time or if that was just a fluke. I'll go with it being a fluke since I've never caught any while crappie fishing. Maybe add some corn to the jig?
