Walleye anglers will agree that when you are fishing for walleye near the bottom it’s tough to outproduce fishing a jig & plastic grub. Anglers for decades have been relying on the “twister-tail” grub which still produces walleye every year, but with such a variety of different plastic grubs on the market when do you use an action tail or no action tail grub.
Here are a few things to consider. If you are fishing deep, fast water and trying to work a jig/plastic grub on the bottom, let’s say like in the Detroit River, a non-action tail grub works best. Any resistance produced by the plastic grub can make it difficult to keep the rig on the bottom (even a non-action tail grub that has a curve in the body). So no surprise that the Lunker City Fin-S Fish is one of the top producing soft-plastics there. Also, if you are fishing in and around isolated weeds, a non-action tail will catch less weeds than an action-tail grub.
On the other hand, if you are fishing shallower, still water that may be turbid, like shallow rocky structure & edges of weedbeds in water less than 15′, than an action-tail will draw fish from a distance and increase your catch-rate. This is where the Lunker City Shaker and Lunker City Swimfish work extremely well. Also remember that plastic grubs with a flapping tail action from side to side will send out more vibration than a curly-tail that swims through the water. Best test is having a good selection of both and using trial and error.
