Super secret technique spolier alert!
If you haven't used split rings for your wacky rigging, you're in for a real exciting fising trip.
Rigging with a stainless ring adds just a touch of weight in the center of the bait allowing it to fall middle-first.  This produces a shockingly wild waving action of the ends of the bait. Like it's flying.  
Fish haven't seen a prey moving this way before and just have to crush it!  
Stainless steel rings specifically sized for the Hex and Big Hex worms.
