This time of year, bass will be shifting much of their focus from the primarily baitfish diet of fall to more crawfish forage. That being said, the fish won’t pass up an easy meal of the finned variety, so it’s wise to keep a Booyah spinnerbait handy.

In colder water, the thump and vibration of your Colorado and Indiana blades will prove more important than the flash and flutter of willow leaf blades. Occasionally, a willow leaf behind a Colorado blade might do the trick, so keep several options handy.

Remember, also, how the combination of line choice and retrieve affects bait performance. For its sinking properties, fluorocarbon is typically the best choice for spinnerbaits, but varying the size varies the running depth.

The lighter the line the thinner the diameter and the faster the fall. Heavier lines with larger diameters fall more slowly because they have greater water resistance.

Combining these principles with varying retrieve speeds gives you even more control. Faster retrieves create more “lift” and bring your bait higher through the water column; while slower retrieves let the bait run farther down in the water — even slow rolling right across the bottom.

Warmer days might find the fish perking up and showing a willingness to pursue a bait moving higher and faster. On the other hand, sustained periods of cold weather will keep the fish’s activity levels low, so make it easy for them to reach — and catch your spinnerbait.
