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 that combines graphite & steel to weight a mere 75grams. This means that the saved weight can be re-distributed to the head of the putter & placed in exactly the right spots to make the head more acute & resistant to twisting at impact. Allowing the golfer to replicate the exact same stroke time after time. This gives an enhanced balance to the putter. The shaft is slightly stiffer & 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.
