What weight jighead are you using? The problem with using the exposed jigheads like that is that the fish can get leverage on the bait with that big leadhead. A fish that big has alot of power when it shakes its head, and it gets those heavier heads swinging side to side. This makes it real easy for that hook to come out of their mouths.

Try using a texas rigged bait like a brushawg or grub or something like that. That way when the fish jumps, the sinker will come up the line and the fish will not be able to get any leverage on that bait when it shakes its head.

Just my 2 cents
hope it helps
