dido beever i was going to say the same thing. I was thinking of trying one on one of my rods if i can find a used one at the flea market.
did you ever use a camera and watch your jig and see it spinning freely at the end of your line. it is because of how the line twists onto the reel on your spinning rod during your retrieve. I have actually watched fish come in really interested in the jigs and look like they get bored waiting for it to stop spinning.
