The new Epic Flash fairway wood features our groundbreaking new Flash Face Technology to help golfers of every level and swing speed get more ball speed and distance. We took the insights we acquired from using Artificial Intelligence (A.I.) and Machine Learning to develop our new Flash Face andFlash Face Sub Zero drivers. And we applied what we learned to create an ultra-thin, forged Carpenter 455 steel clubface for Epic Flash fairway woods that incorporates our renowned Face Cup technology and our new Flash Face technology. The result is a uniquely designed clubface thats expressly engineered for high COR across a large area, to promote fast ball speed on both center and off-center hits. New Flash Face Technology for Faster Ball Speed. Callaway engineers used Artificial Intelligence and Machine Learning to create a radically different face design to promote faster ball speed in the center region of the face. Jailbreak Technology for Faster Ball Speed. Internal Jailbreak bars stiffen and stabilize the crown and sole, placing more impact load on the face to promote faster ball speed. Forged Carpenter Steel Face Cup for Fast Speed. Forged 455 Carpenter steel construction combines with Face Cup technology to deliver fast ball speed across the face for distanceon center- and off-center hits.
