I like to use the 3.5" ZZ Swayback swimmer.

I have used spinnerbait twin tails on them over grass and caught some good fish doing that. Almost anything you want to put on it. I sometimes fish them with a skirt, deep and stop and go retrieve and get HAMMERED with the fish strike there. Hope this helps. Tight lines, keep safe and good luck.

PS, Casey Ashley won the Classic on a underspin head last year.

PPS. I use Spotsticker underhead spins.

I like Joey's because you can fish them weedless or extend the hook out the back of the bait by using the screw lock system. Changing out the willow blade is as easy as changing a spinner bait blade. One under spin held up in Mexico with 25 Bass over 5 lbs. no problems. I did change out the screw lock to a magnum size with the spike in the center for a faster and more secure loading of a 6" swim bait.

thank you everyone while im mastering this new device ill use swim baits and flukes when it gets slow and i really like the under spin swim bait hooks im getting some now
