I just switched from O Rings to electrical tape. Just get a piece of tape to match the color of your senko. Split the tape in half (the long way) since its so thick, and wrap it around your worm. Then take your hook and stick it in the tape on one end through the worm and out the tape on the other side. All you will have is a small hole the tape really holds the hook in place. Or just switch to a different stick bait other than the super salty senkos.
