The TENSEI™ AV Blue Series modernizes MCA GOLF’s tour-proven, classic smooth bend profile. Aluminum Vapor Coated Fiber in the butt section adds stability, to help achieve the desired EI target and stiffness. Compared to the previous TENSEI™ CK Series, this is slightly lighter throughout, with a lower torque. And the AV weave is tighter and thinner, to help prevent shaft ovaling and improve energy transfer. The lightest of the three weight options also incorporates the Straight Flight Weighting (SFW) system that helps golfers turn the club over easier through impact, which in turn straightens a slight fade or promotes a slight draw.
