4" Spring Shad 40 (sink) - THREADFIN SHAD Since there is no lip on the bait & small in size, it will need more current to make bait swim right. If casting, you will need to use it like a jerkbait. Give it a small twitch or big jerk to make it move side to side. You can also use it like a spoon by using a yo-yo retrieve so it will flutter down like a wounded bait. Rate of fall is one foot per second. For trolling, troll at 2.5-3.0 mph speed to make bait swim straight.
