Spinnerbaits come in various blade types, and each has its own unique action and appeal to fish. The most popular blade types for spinnerbaits include Colorado blades, Willow blades, and Indiana blades. Colorado blades are known for their slow and steady rotation, making them ideal for attracting fish in low visibility or murky water. Willow blades, on the other hand, have a narrow profile and provide a fast, flashy spin. They are excellent for clear water and imitating fast baitfish movements. Indiana blades fall in between Colorado and Willow blades when it comes to both speed and vibration. Experimenting with different blade types can help you determine which works best for the conditions you'll be fishing in.
