Downsize or downsize that's normally the answer.

Had the same issue for a long time, changed to a leader and from 1/8 to 1/16 and lost the roadrunner head/spinner. Started catching right away. I kept changing back more to my original set up and the only thing that made a difference was a little lighter jig head and slimmer profile body. The fish cared about noting else. I was so happy no leader needed! Back to straight braid and probably could have wemt back to a 1/8 also but never did. I use a weight above the jig to get down faster.

Shad Assassin worked for me! Link below.
