Odyssey White Hot XG Marxman Mallet. New for 2007. The Odyssey White Hot XG Marxman Mallet is a face-balanced alignment mallet with perimeter weighting, a double-bend shaft and full-shaft offset. This, the next generation in White Hot Technology, utilises a multi-layer insert that takes feel, feedback and distance control to the next level. The multi-layer insert combines soft, resilient elastomer core with a thin, firm urethane cover to deliver exceptional feel and feedback. Insert Technology allows weight to be shifted to the perimeter of the head for a high MOI, creating better forgiveness and a truer roll. The soft, highly resilient core enhances feel, gets ball rolling quickly while the thin, firm cover gives exceptional feedback.
