If you have confidence in the specific jerkbait your throwing, dont change it!!! Just insert the rattle, take it back out, then drop a dab of superglue on it and re-insert it. You should be good to go!
Good luck, man! Soft plastic jerkbaits are one of my confidence baits and like ww2farmer said, the Yamamoto d-shad KILLS the fish. I also really love the Zoom superfluke in smokin shad. I rig all mine with a 3/0 Gamakatsu ewg, 8lb fluoro, and a Spro barrel swivel about 10" up the line. Twitch, twitch, pause, twitch, pause, repeat,,,,that is, if a fish hasn't already engulfed it!!!
