The role of the sole tends to be a little under appreciated when it comes to forgiveness, and especially in the realm of super game-improvement irons, clubs whose users tend to hit the big ball (the earth) before the little ball a little too often.
Sometimes a product line is so successful, its longevity leads to some iterations that stray somewhat from its original intent. Callaway’s introduction of its Big Bertha B-21 irons and hybrids aims to rectify that.
There are not many companies, if any, that can introduce five sets of irons at one time – throw in a specialty set of long-iron replacement hybrids to boot – and still make you believe that each has its place. But that’s precisely what Mizuno has done with its next iteration of its modern JPX lineup.
