The Verdict: Bad things can happen with ultra-forgiving drivers. Either they look and sound hollow and cheap, or worse, by pushing weight to the extremes, the center of gravity relocates upward, resulting in too much ball spin. M2 combats those problems with a weight-saving, carbon-composite crown on top and a reconfigured internal geometry. This provides forgiveness and keeps the CG low. Meanwhile, more curvature on the sole (note the overhang where the crown and sole meet) helps mellow the sound. Of course, they didn’t forget about power: A sleeker slot in the sole deflects three times as much as before.
