Here's what you do: take your putter and grip it with two fingers on the handle. Next, swing the putter back and forth in the air like a pendulum. Now, tap the putter face with your finger and see where it bounces back from. If the putter returns straight, congratulations! You've hit the sweet spot. But if it deflects to the left or right, don't worry, it just means you have some more tapping to do until you find that magical spot. The sweet spot is where you'll get the perfect balance between power and control for your putting strokes. So, keep tapping until you find it!
