More importantly, however, the hook spins freely on its post, thus eliminating the need for the separate barrel swivel. That means your line won't twist and your lure gets a lot more action. It'll also helps you land more bass by reducing pressure during a fight since the hook will spin with the fish. I'd say the SpinShot is a great example of a tiny improvement that can make a big difference in presentation. VMC is selling them in six sizes, and they'll cost you $4 for a pack of five. Look for SpinShots on the shelf this fall.
