Double Overlap: Jim FurykWhat It Does: Quiets overall hand action. It's a great match for Furyk's swing because his signature loop puts him in danger of over-curving the ball if his hands work too hard or fast.
How to Do It: Wrap the last two fingers of your right hand over the last two fingers on your left hand.
You know you need it if: Your swing is too "handsy" or you tend to throw the club at the ball. It requires stronger hands and reduces distance, but it's definitely a fairway-finding grip.
