Go to the auto store like pep Boys and look at the section that has carburetor springs. You can find a whole bunch of different sizes to suit your needs. Drill a hole in the back of the bait and epoxy the spring in. Stretch the spring so the threads are seperated. Twist your favorite tail on and it will stay. The springs will also flex a little back and forth to add to the action. You can also add a little super glue if you want added adhesion.

I have also just gotten a wood screw and screwed it in to the rear of the bait. Next, cut off the screw head and twist on your bait. A little gue will help it hold good. GOOD FISHIN. It's the time to fling it and bring it !!!!
