While many putting grips can work for you, you need to choose one that helps you keep the putterface square and on line as it passes through the ball. In addition, the putting grip should minimize hand and wrist action. You can easily tell of your grip stays on a straight line with a simple test. Play the ball up in your stance and see if you are putting it to the left. Then play it back in your stance and see if you are putting it to the right (Reverse for left handers). Try different grips till there is little difference whether you play the ball up or back in your stance.
