Lofts compared

What the differences mean
At the 7-iron, the Elyte X is 28° and the Quantum Max OS is 29°, a 1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the Elyte X should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the Quantum Max OS. Across the 10 clubs both sets share, the Quantum Max OS averages 1° weaker, with the largest gap at the 4-iron (18° vs 19°). The pitching wedges are 41° and 42°; the stronger one leaves a 9° jump to a 50° gap wedge, which matters when planning wedge gapping. Beyond loft, the Quantum Max OS 7-iron sits 0.2° flatter (62.5° vs 62.25°), which nudges start direction slightly right for a right-hander.
The Elyte X is a game improvement iron and the Quantum Max OS a super game improvement iron, so they sit one step apart on the forgiveness scale. The Quantum Max OS is the more forgiving design, with a wider sole, more offset and more perimeter weighting for high handicaps, beginners and slower swing speeds. The Elyte X trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly 10 to 25 handicaps.
The Elyte X is listed as Speed Frame cast body with an Ai 10x face and the Quantum Max OS as two-piece Modern 360° Undercut cavity body with a Progressive Tri-Sole and urethane microspheres. With the build method this similar, differences in feel come down to head size, sole width, topline and offset rather than how the heads are made.
The Quantum Max OS arrived 1 year after the Elyte X, a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept. Here the 7-iron loft moved from 28° to 29°.
Which should you choose?
The Quantum Max OS is the weaker-lofted set — up to 1° weaker than the Elyte X. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.
