C523 HYBRID A new sole rail design on all C523 metals that extends from leading edge to trailing edge. The new sole rail design produces a super-low CG for high-launching shots with optimized spin rates, decreased turf interaction and maximum ball speed off the face. The rail design lowered the CG and allowed for a 36% increase in hitting area on the face of the fairway, making it easier to achieve greater power and increased forgiveness. A back weight is strategically placed to the extreme rear of the clubhead that places more mass at the extreme trailing edge of the clubhead. The back weight creates an extremely high MOI rating, an 11% increase over the previous iteration, for top in-line stability. This weighting dramatically affects a lower and deeper CG positioning of the club for ease of launch and more forgiveness off the face at impact. The Power Channel on the sole of the club behind the club face is strategically deeper and wider in the C523 design. The 90% larger Power Channel featured on the C523 Hybrid distributes weight to promote increased face flexing, amplified ball speed and less spin, as well as added forgiveness on shots struck lower on the face. Diamond Face Variable Face Thickness technology is a breakthrough in face technology that features 39 different thick and thin diamond shapes or "mini-trampolines" behind the face. Diamond Face VFT produces a hotter face with faster ball speeds and better performance on off-center hits, as well as reduced spin. The more compact profile and deeper face of the C523 Hybrid were designed with the competitive player in mind. The C523 Hybrid design sits open and has a more pear-shaped traditional design that player's look for at address. This versatile hybrid will play from the tee, fairway, rough and around the green.
