The new Stroke Lab Tuttle putter from Odyssey is a classically designed, mallet headed putter with three straight lines running from putter face to the rear of the putter head which makes putt alignment incredibly easy to do. The putter head has 2 weights in the sole to give the head more weight. There is also extra weight in the putter grip area. That is because the Stroke Lab shaft is 40g lighter than previous shafts used. Made from graphite with a steel tip, this shaft is slightly stiffer than its predecessor. All of this ensures that the perfect balance is struck to ensure that this putter feels as good as can do in your hands.
