When I fish my Senkos Wacky, I use an O-ring because it increases the longevity of the bait. Commercial O-rings work well for the 3″, 4″, 5″, and 6″ Senko. Ironically, I lose many 7″ Senkos. I think it’s because when fish tugs at one end, it’s mass contributes to it’s inertia. After retrieving several O-rings without Senkos, I started making my own Wacky O-Rings for 7″ Senkos.

Making your own Wacky O-Rings is easy with some some simple tools. First, cut a 1/2″ wide section from 1/2″ round heat shrink tubing via scissors.

Second, insert the Senko through the 1/2″ heat shrink section. Pinch the Senko such that a gap is formed between the Senko and the heat shrink tubing. Insert your hook through the heat shrink tubing without penetrating the Senkos.

Lastly, hold the hook with a pair of pliers and apply just enough heat via heat gun to shrink the tubing around the hook. Gently lay the Senko down and allow the tubing to cool. If you move the hook while the tubing is hot, the holes around the hook will enlarge.

This DIY Wacky O-Ring works well for any size Senko and other soft plastic stick baits. You just need to adjust the diameter of the heat shrink tubing accordingly. You can use grey electrical heat shrink tubing or clear marine heat shrink tubing.
