Overall, the Epic Speed has been engineered to create speed and distance. First, the Epic Speed features Callaway’s Jailbreak A.I. (Artificial Intelligence) Velocity Blades to stiffen the golf club body for more stability through impact. Second, Flash Face SS 21 on the Epic Speed fairway wood bolsters off-center strikes and hopefully retains ball speeds across the club face. Third, forged C300 maraging steel face cup technology increases face flexing that can create longer shots and more spin consistency as strikes vary. Lastly, Epic Speed fairway woods have forward centers of gravity to create a penetrating, lower spinning ball flight.
