Lofts compared
- Fly-Z
- KING F6
What the differences mean
At the 7-iron, the Fly-Z is 30.5° and the KING F6 is 30°, a 0.5° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the KING F6 should carry about 2 yards further with that club, on a slightly lower, shallower flight than the Fly-Z. Across the 10 clubs both sets share, the differences roughly cancel out, with the largest gap at the 3-iron (17° vs 18°).
The sets are built differently: the Fly-Z runs 3-iron to LW (11 clubs), the KING F6 3-iron to SW (10 clubs).
Both are game improvement irons, built for roughly 10 to 25 handicaps. Perimeter-weighted cavity backs with wider soles, more offset and stronger lofts, aimed at mid handicaps. 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.
The Fly-Z is listed as investment cast undercut cavity back with welded face insert and the KING F6 as progressive TECFLO set — full hollow long irons, half hollow mid irons, cavity back short irons, specialty wedges. The KING F6's hollow body lets the face flex more and moves mass low and outward, usually giving higher launch and more ball speed on off-centre strikes than the Fly-Z, at some cost in feel.
The KING F6 arrived 1 year after the Fly-Z, 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 30.5° to 30°.
Which should you choose?
The KING F6 is the stronger-lofted set — up to 1° stronger than the Fly-Z on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.

Frequently asked questions
Is the Cobra Fly-Z stronger lofted than the KING F6?
No. The KING F6 is the stronger-lofted set: its 7-iron is 30° against 30.5° for the Cobra Fly-Z, 0.5° stronger and worth about 2 yards of extra carry.
What is the loft difference between the Cobra Fly-Z and KING F6?
At the 7-iron the difference is 0.5° (30.5° vs 30°). The largest gap on a shared club is 1° at the 3-iron, and 5 of the 10 shared clubs differ.
Are the Cobra Fly-Z and KING F6 aimed at the same golfer?
Yes. Both are game improvement irons, built for roughly 10 to 25 handicaps. Choose on feel, looks and gapping, ideally after hitting both.
Do the Cobra Fly-Z and KING F6 have the same lie and length?
At the 7-iron, yes: both are 62.5° lie and 37.25 inches long.
