Go to the range at a pro tournament and you'll see countless players practicing with an arm connection ball.
Back in the day, Nick Faldo used a volleyball between his arms. Nowadays, you'll see major champions like Rory practicing with the modern day version.
But it's not reserved for the elite. If anything, the everyday slicer needs it more. Tour pros use it to maintain a connected move they've spent years building.
Maybe you're a beginner who slices every club, or a single figure player who only fights the driver. Either way, the Performance Ball gives you the feeling of a connected, inside path, and once you feel it, you can't unfeel it.
