Which to choose

The biggest difference reviewers report is launch. The ZXi5 is generally described as launching high, especially in the long irons. Testers were split on the ZX5 Mk II, and some saw a lower launch than they wanted. Otherwise the published 7-irons are almost the same (31° loft, 62° lie, 16° bounce). The ZXi5's 7-iron is slightly longer, at about 37.25 inches against 37.0 inches.

Feel differs too. The ZX5 Mk II is consistently called crisp and solid, while opinions on the ZXi5 range from soft to firm. Spin reports are mixed for both, and some testers said the ZXi5's short irons spun too little to hold firm greens. The ZX5 Mk II has a simple chrome finish, while the ZXi5's black-and-white finish shows scuffs.

Choose the SRIXON ZX5 Mk II Irons if…

Choose the SRIXON ZXi5 Irons if…

you want a higher launch, especially from the long irons, along with strong, consistent ball speed through the set, or you want to pair it with the ZXi7 in a combo set.

Side by Side, Aspect by Aspect

Launch: the ZXi5 Is More Often Called High

For the ZX5 Mk II, one reviewer described a good, reliable flight, and one testing video said it launched the ball high, particularly in the 7-iron and 5-iron. Another video found the mid and long irons launched lower than expected for their loft, though the 5-iron launch was good. A further tester praised a consistent flight that held up well into the wind. For the ZXi5, two reviewers reported high launch, one even on less-than-perfect strikes and one especially in the long irons. A third called it mid to mid-high. Reports on the ZX5 Mk II are split, while most ZXi5 reports point to a higher flight.

Spin: Mixed Reports for Both Sets

On the ZX5 Mk II, one reviewer rated spin as good and noted deeper grooves in the short irons to add spin. One tester found spin slightly higher than his previous irons in the 9-iron. In two testing videos it fell short: one saw spin drop off on indoor mats, especially in the 5-iron, and another got less backspin than he wanted, though he still called it usable. The ZXi5 is just as divided. One reviewer found spin too low to stop the ball on dry greens, another called it good apart from the short irons, and a third rated it strong and steady. Neither model has a clear edge on spin, and both have been criticised for low spin by some testers.

Feel and Sound: ZX5 Mk II Crisp, ZXi5 Varied

All four sources on the ZX5 Mk II praised its feel. One reviewer called it crisp and firmer than the original ZX5 but still forged, and testers described good feedback and touch around the greens. Sound was rated well throughout, from a crisp, mid-volume tone to a solid, loud, pleasing one. Descriptions of the ZXi5 vary. One reviewer heard a firm click and said it is not the softest iron, while two others called it soft. A testing video described a medium, punchier feel. One reviewer found the sound rich and solid, but said it fades on toe and heel hits. The ZX5 Mk II earns more consistent praise for feel and sound.

Forgiveness: Both Rated Strong, ZXi5 Toe Caveat

Every source rated the ZX5 Mk II as forgiving. One reviewer said milled channels move weight to the toe and sole, so mishits lose some distance but not much, and thin strikes still get airborne. Testers called it consistent and said off-centre shots still flew fairly straight. The ZXi5 also scored well: reviewers described only a small loss of distance and dispersion on mishits and a predictable flight, and one credited its wider sole and rear weighting for higher MOI. One testing video, though, found it clearly weaker on toe strikes than its newer successor, while heel and low strikes were very forgiving. Both are seen as forgiving, but the ZXi5 has one specific reported weakness on toe strikes.
