The neko rig is similar to the wacky rig, except it includes a weight on one of the ends of the soft plastic bait. The weight anchors one end of the bait to the bottom, while allowing the other end to float freely. The rig also provides the bait a unique movement that attracts fish as it falls downward through the water column.
To create this rig, first take a soft plastic and make a wacky rig. Then, take one of the end and insert a drywall screw, finishing nail, or 3/32 to 1/8 ounce weight. The extra weight gives this rig an interesting zippy movement and also helps it reach the bottom more quickly.
