The new Odyssey Stroke Lab Ten S Putters help to improve the entire swing through a significant change in weight distribution made possible by a newly engineered shaft. The Stroke Lab shaft is 40 grams lighter than a traditional steel putter shaft, this new dual-material shaft combines graphite and steel to weigh a mere 75grams. This means that the saved weight can be re-distributed to the head of the putter and placed in exactly the right spots to make the head more acute and resistant to twisting at impact. Allowing the golfer to replicate the exact same stroke time after time. This gives an improved balance to the putter. The shaft is slightly stiffer and has a lower torque. This helps to stop the head from twisting at impact. the Ten S has a slightly different shaft/head configuration to get the leading edge of the putter a little further back relative to the shaft.
