Hi I’m Kelly Jordon, Team Yamaha Pro. When you’re using crank baits fishing for bass, always use the smallest line you can get away with. It helps you get more depth, and also the bait swims in a more natural fashion. And it’s really important to use as light a line as you can get away with, taking in all the factors, like cover, that you’re going to be around, you know what you need. I generally start around 10 or 12 pound test.By: Walker Agency
