Odyssey White Hot XG 2-Ball SRT Putter The Odyssey White Hot XG SRT Putters combine a multi-layer insert with Saturn Ring Technology to give you phenomenal performance with any golf ball. Inspired by high-performance golf ball technology, the White Hot XG insert takes two materials with different properties and combines them to take the level of feedback and feel to an all-new high. Saturn Ring Technology features a high-density alloy ring weighting system and a lightweight milled aluminum body that precisely place the putter's center of gravity (CG) and dramatically increase the Moment of Inertia. And with the tour-proven 2-Ball alignment system, lining up putts is easier and more accurate. Features: High-Density Alloy Saturn Ring Weighting system provides an optimum CG location for a truer roll and an enormous MOI to help keep the putter on-line during the stroke Lightweight Milled Aluminum Body allows for distribution of weight to the perimeter of the head for better stability
