In-Line Spinners work great for largemouth bass, especially during the spring time when bass are feeding on smaller bait fish. On good bass lakes, you can expect to catch a lot of bass with in-line spinners, although, most of the bass will usually be small to average-sized with some big ones mixed in. Don’t be discouraged with the smaller bass. The big bass will still bite this lure. It is just an appealing lure to small bass as well.
