Lofts compared

- X-20 Tour
What the differences mean
At the 7-iron, the X-18 Pro Series is 33° and the X-20 Tour is 34°, a 1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the X-18 Pro Series should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the X-20 Tour. Across the 9 clubs both sets share, the X-20 Tour averages 0.6° weaker, with the largest gap at the 5-iron (26° vs 27°). Beyond loft, the X-20 Tour 7-iron sits 0.5° flatter (62.5° vs 62°), which nudges start direction slightly right for a right-hander.
The sets are built differently: the X-18 Pro Series runs 2-iron to LW (12 clubs), the X-20 Tour 2-iron to PW (9 clubs).
Both are players irons, built for roughly scratch to 10 handicaps. Small-to-mid cavity backs with traditional lofts, modest offset and workable shaping for low-handicap players. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.
Both heads are listed as investment cast. 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 X-20 Tour arrived 3 years after the X-18 Pro Series, 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 33° to 34°.
Which should you choose?
The X-20 Tour is the weaker-lofted set — up to 1° weaker than the X-18 Pro Series. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.
