Stroke Lab is about challenging common, well-established putter norms with innovative ideas that promote better performance. The new Stroke Lab line of putters incorporates a unique new method of weight distribution designed to improve the physical dynamics of the stroke. The Stroke Lab shaft is a full 40 grams lighter**, made possible by an innovative new multi-material shaft design that combines agraphite body with a steel tip to net out at just 75g, with most of the mass concentrated in the tip. Weve redistributed thatsaved weight by adding 10g to the head in the form of two sole weights, and adding 30g to the grip-end via a 10g-lighter grip and 40g end-weight. The effect of Stroke Labs innovative weight distribution on the stroke is dramatic. Odyssey studies indicate improvements in the consistency of backswing time, face-angle at impact, ball speed, and ball direction. Feel for the putterhead becomes more acute, helping the golfer repeat the same, smooth stroke time after time. You feel the difference immediately, said Luke Williams, senior director of putter marketing. The putter head moves freely, smoothly and on a sound path, helping you roll the ball accurately while giving you greater speed-control.
