Lofts compared
- Steelhead X-14
- X-16 Pro Series
What the differences mean
At the 7-iron, the Steelhead X-14 is 33° and the X-16 Pro Series 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 Steelhead X-14 should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the X-16 Pro Series. Across the 11 clubs both sets share, the differences roughly cancel out, with the largest gap at the AW (52° vs 50°). The pitching wedges are 46.5° and 46°; the stronger one leaves a 4° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the Steelhead X-14 runs 3-iron to LW (11 clubs), the X-16 Pro Series 1-iron to LW (13 clubs).
The Steelhead X-14 is a game improvement iron and the X-16 Pro Series a players iron, so they sit 2 steps apart on the forgiveness scale. The Steelhead X-14 is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 10 to 25 handicaps. The X-16 Pro Series trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly scratch to 10 handicaps.
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-16 Pro Series came out 2 years after the Steelhead X-14, but it is a different line rather than a direct replacement, so the two were designed for different golfers as well as different seasons.
Which should you choose?
The X-16 Pro Series is the weaker-lofted set — up to 2° weaker than the Steelhead X-14. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.
