The newly re - engineered INOVAI 6.0 Spud 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 6.0 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 6061 Military Grade Alum inum body, with a new Stealth Black anodized finish. The INOVAI 6.0 is offered in three unique neck options, including spud, slant, and center shaft. The INOVAI 6.0 has consistently been in play by multiple Bettinardi staffers on Tour since its initial rel ease in 2020.
