Cobra King F6 Irons Review: ClubTest 2016

March 11, 2016



CATEGORY: Game Improvement Irons
PRICE: $800, steel; $900, graphite
WE TESTED: 4–GW with FST steel shafts; 2-3 hybrid (adjusts 16° to 19°), 3-4 hybrid (adjusts 19° to 22°) and 5–PW with Matrix Red Tie 65Q4 graphite shafts; 3-4 hybrid (adjusts 19° to 22°), 4-5 hybrid (adjusts 22° to 25°), and 6–GW with Matrix Red Tie 65Q4 graphite shafts
KEY TECHNOLOGIES: This set uses four different head styles: hollow long irons, half-hollow mid-irons, cavity-back short irons and solid, one-piece wedges.


PLAYABILITY: A high-launching set that lifts you out of trouble; stable and effective from the rough; responds to basic commands; hybrids provide tons of help — and value.
ACCURACY/FORGIVENESS: One of your better options, not much miss in these clubs; a great mix of easy and accurate — allows some sidespin without overdoing it; mid-irons and hybrids fly straight and land soft, even when you don’t pure ’em.
DISTANCE CONTROL: Above-average on all contact; exceptional consistency for a combo set — regular gaps make them easy to lock in; plenty of control with wedges; for a few guys, the hybrids fly farther than expected.
FEEL: Steady, coherent feel throughout the set, despite its mixed makeup; toned-down shock absorbers; stock graphite shafts hold up well to most swings and feel stable — the turf doesn’t stand a chance.
LOOK: A seamless progressive set; meaty topline and encouraging offset sit well behind the ball; hybrids are compact and easy to align.


For some, they’re all a little thick over the ball and a little tongue-tied at impact; one or two testers think the two-tone appearance comes off a little less serious than most; a few guys find the graphite shaft too light and tricky to time.

BOTTOM LINE: The Cobra King F6 irons are a blended set that matches different head styles in rare harmony. They’re easy, they’re accurate, and the complementary hybrids are as good as anything on the market.



From, November 17, 2015:

The new King F6 irons are built with a progressive design aimed at optimizing each segment of the set; the long irons (3-5) feature a full hollow cavity design for maximum distance and forgiveness, the mid irons (6-7) feature a half hollow construction for a combination of distance and control, and the short irons (8-PW) are built with a cavity back design for spin and control. The shorter wedges in the set are traditional and are optimized for versatility and maximum spin.

Each segment of the set also features a different type of milled groove to optimize spin rates. To further improve the performance of the long and mid irons an aluminum insert is placed in back of the cavity to shift more weight (10g in the long irons, 5g in the mid irons) lower and deeper in the clubhead, producing higher launch angles and improved forgiveness. Enhanced ballspeed and distance come from a channel behind the clubface and in the sole that provide increased face flex. — Michael Chwasky
