The Bettinardi Counterbalanced BB Series features designs to fit any taste and provide an alternative to an anchored putting stroke. By adding length and weight in the shaft, matched by added weight in the head, these putters have an increased moment of inertia resulting in a smoother, more stable stroke. The BB55 Counterbalance is a heel shafted mallet putter that weighs 395 grams. This putter is face balanced, making it great for players with a straight-back, straight-through putting stroke.
