Typically the biggest post spawn females are tired and sluggish, making them reclusive. They really don't want to spend any more energy than they have to. So putting the bait right in front of their faces is key. They're usually at the first deep water access that was near their spawning grounds. Those areas are secondary points, pre spawn bluff walls, humps, and basically anything that has deep water close by. Any place you caught pre spawn fish, you can usually catch post spawn fish there too. They follow the same routes.Roboworm Alive Shad
I like to throw one these on a drop shot and just kinda drag it around. A drop shot allows you to keep your bait in the strike zone for a long time, which is what you want for those sluggish females. The Alive Shad mimics a shad, bass fry, or small bluegill very well. It floats and has lots of action, enticing even the peskiest bass. Phenix Vibrator Jig Version III
If you really want those bigger bites, then I suggest you throw the Phenix Vibrator Jig Version III. Vibrating jigs are known for catching bigger fish than other baits. This is especially true throughout all stages of the spawn. The great thing about these jigs is that they're high quality and will stand up to rigorous abuse. Thread a super fluke on the back and you're ready to go!
