The newly re-designed INOVAI 6.0 Center Shaft was designed by Sam Bettinardi to perfect our most successful M.O.I. (Moment of Inertia) mallet to date. With two years of Tour feedback, Sam refined the 5.0 with a 5% smaller head from heel to toe, offering a sleek, more compact design than its predecessor. The 358 gram 6.0 features a precision-milled Roll Control face from 303 Stainless Steel and a 6061 Military Grade Aluminum body, with an all-new Stealth Black anodized finish. The center shaft offers a face balanced option in this Tour-winning lineup, ideally for players with a straight-back, straight-through putting stroke. The INOVAI 6.0 has consistently been in play by multiple Bettinardi staffers on Tour since its initial release in 2020.
