Loft is the real separator. The Callaway Quantum Max Fast runs its 7-iron at 26.5 degrees, 2.5 degrees stronger than the Cobra KING MAX at 29 degrees, which works out to roughly 6 yards more carry at the same swing speed. That extra distance comes with a gapping question at the bottom of the bag, since the Quantum Max Fast pitching wedge sits at 40 degrees against 42.5 degrees for the KING MAX. The KING MAX stock set starts at the 5-iron, while the Quantum Max Fast data starts at the 6-iron, so a golfer who wants a long iron gets one from Cobra without adding a hybrid. Both are hollow body, wide sole, high launch designs at the same $999 price. Callaway pairs its shape with an AI designed face. Cobra uses a face insert instead.
Pick the Quantum Max Fast if distance is the priority and you are willing to sort out the gap into your wedges. Pick the KING MAX if you want a fuller set with a 5-iron included and weaker lofts through the set, which leaves an easier gap into your wedges. Price does not decide this one, since both sets list at $999. Feel is the open question, so hit both before buying.
