Callaway’s Rogue line for 2018 adds the a hybrid with the same “Jailbreak” technology that made last year’s Epic Driver such a big hit. Two steel bars stiffen the body, placing more impact load on the face. That increases ball speed and distance. Callaway’s Cup Face design helps to maintain across the face. And finally, an “Internal Standing Wave” lets Callaway lower the center of gravity for better launch conditions.
