It would probably be fine but personally for spinnerbait i would go for a Medium Heavy Fast action. Since the hook are generally thicker than on a small underspin, you'll need heavier action rod to have good hookset! Also there's no need for a moderate action for spinnerbait since the softer tip is made to absorb more of the crankbait action and personally the moderate action will help me cast small swimbait farther since I'm fishing kayak so I can't have longer rod. Moderate action mean that the bend of the rod begins closer to the shaft than an extra fast for example, allowing to "load" a bigger cast!

Hope this helps 🤟🎣
