There's a lot of debate on whether or not you should use a swivel with a Rooster Tail. The main argument for using a swivel is that it prevents the line from getting tangled. However, some people argue that the swivel actually decreases the effectiveness of the lure, because it can cause the bait to spin. Ultimately, it's up to you to decide whether or not to use a swivel with your Rooster Tail. If you're concerned about line tangles, then go ahead and use one. But if you want your lure to work its magic unhindered, then ditch the swivel and let it fly!
