The biggest difference is head type. The Z-Forged II is Srixon's traditional forged muscle-back blade. The ZXi7 is a forged players' cavity-back that sits between the blade-like options and the more forgiving ZXi5 and ZXi5+. Testers disagree about how forgiving the Z-Forged II is: some call it low, as you'd expect from a blade, and others found mishits held up better than they expected. On the ZXi7, most testers still found off-centre strikes playable.
Both irons shape shots easily and feel soft and solid. The ZXi7's 7-iron is slightly stronger at 32° against 33°, and slightly longer at 37.25 inches against 37.0 inches. The ZXi7 is built to blend with the ZXi5 and ZXi5+ in combo sets. With the Z-Forged II, a fitting that adds cavity-back long irons is recommended.
