The #1 thing I consider when fishing a spinner is what kind of vibration it’s throwing off. I think the vibration is often the first thing a walleye detects from a lure coming by him. So if you’re using a spinner that is putting out the right vibration, you have a better chance of attracting a walleye and getting him to bite.
For that reason, I like to use a Quick Change changeable clevis on spinners. Its a small plastic clevis that allows you to snap on a blade, or easily remove it and snap on another blade. That lets me change the size and shape of blades easily, and quickly experiment to find out what vibration is going to trigger the walleyes on that day.
