Soft Plastic Minnows work excellent for spotted. There are so many good ones to choose from that give anglers a chance to target bass shallow with a weightless rig, deep with a drop shot rig or around all types of cover with a shaky head jig. Some of the best soft plastic minnows are in the 3 to 4 inch range, but don’t rule out some of the bigger minnow baits in the 5 to 6 inch range either.
Swimbaits work well for spotted bass. The smaller 4 to 5 inch swimbaits are better baits because of the smaller mouths that spotted bass have. However, anglers do report that spotted bass will attack some of the bigger swimbaits too. For more action, go smaller and you’ll be glad you did.
