Odyssey Stroke Lab R-Ball Putter Stroke Lab is about challenging common, well-established putter norms with innovative ideas that promote better performance. The Stroke Lab Putters incorporate a unique new method of weight distribution designed to improve the physical dynamics of the stroke. Most golfers’ putting strokes are inconsistent. Yet most putting technologies focus on improving alignment or improving the quality of roll. They attempt to mask a given stroke’s weaknesses instead of improving those weaknesses. Odyssey’s Stroke Lab putter line actually helps improve the golfer’s stroke, including backswing length, face angle at impact, head speed through impact and tempo, all through a profound change in weight distribution made possible by an innovative new shaft. This is a completely new approach to putter weighting, and only Odyssey has it. A face-balanced mallet, the Odyssey R-Ball is a face-balanced mallet design with a multi-material Stroke Lab shaft, R-Ball alignment, and a White Hot Microhinge face insert. Multi-material Stroke Lab Shaft for Innovative Weight Distribution Tip-heavy graphite and steel shaft saves 40 grams* that’s relocated into each end of the putter to change performance dynamics. Slightly Stiffer and Lower Torque for Increased Control The Stroke Lab shaft is slightly stiffer and lower torque compared to standard putter shafts to better control the slightly heavier head. Sole Weights and Grip Weight for a Smooth and Accurate Stroke Additional weight in the sole and butt-end of the grip change the putter’s dynamics to help golfers consistently repeat a smoother and more accurate stroke. White Hot Microhinge Face Insert for a Great Feel and Smooth Roll Combines legendary White Hot feel with dozens of microhinges embedded across the face that promote topspin for smooth roll and acute distance control.
