The Callaway Apex Ai150 and the Srixon ZXi7 share the same $1149 MSRP, the same players cavity category and the same MyGolfSpy score of 86/100, so the differences come down to construction and loft. The Apex Ai150 is a forged hollow body iron with an AI Designed Face, and it runs 3 degrees stronger at the 7-iron, 31° against 34°. That works out to roughly 7 yards more carry at the same swing speed, which means you should look closely at wedge gapping below the 45° pitching wedge. The ZXi7 is a forged cavity back with Progressive Lofts and Vibration Dampening, and its stock set starts at a 20° 3-iron, where the Apex Ai150 data begins at the 4-iron. Golf Digest gave the Apex Ai150 92/100 and the ZXi7 78/100.
If distance is what you want from a players cavity, the Apex Ai150 is the pick. Its stronger lofts and hollow body point that way, and its higher Golf Digest score adds weight. Choose the ZXi7 if you prefer a traditional cavity back, want the option of a stock 3-iron, or would rather keep more conventional lofts and feel over extra yards. Price will not separate them. Feel and set makeup will.
