Cobra King F9 Speedbacks I love them
By Paul C. on 5/26/2020
17 out of 18 people found this review helpful.
Handicap: 11-15  Plays Golf: I play weekly  Dexterity: Right Hand

Prior to this purchase (4-GW), I would never have believed that the clubs made that big a difference in my game. However, my results speak for themselves. I also use the Cobra King F9 driver. The clubs have a very nice feel and sound. I turn 69 in July. And no, I am not your usual senior citizen (personal trainer).

With my old clubs I hit my GW about 105 yds. With my F9s, about 130 - 135.

I hit my PW about 120 yds, but with the F9, about 140 - 145.

The increases follow for all my clubs. I am thoroughly impressed.

The guys I play with are very interested in the King Cobra F9s.

Handicap: 6-10  Plays Golf: I play more than once a week  Dexterity: Right Hand

These Cobra King F9 irons were my second purchase of Certified Clubs offered from Global Golf. These irons were in perfect (like new) condition. These irons feel great and are long and very accurate. Buy Certified and save $$$$.

Clubs good; delivery horrible
By John V. on 8/9/2020
1 out of 1 people found this review helpful.

Clubs are really great, but delivery was two weeks late. After being one week late, I contacted global golf and they promised to overnight a set. A week later the first set finally arrived and then a week after that, the second set. So much for "overnight". I then had the hassle of sending back the 2nd set. GG was helpful on the phone in getting through it all so that was good. I think it was the postal service that dropped the ball the most.

Cobra King F9 Speedback Irons Overview

Back of iron head

Speedback Design

The speedback design adds mass to the lower and wider parts of the club, lowering CG and allowing players to maximize ball speed while still having a conventional size sole width.

inside and back of iron head removed

Multi-Materail Medallion

The three materials in the speedback iron medallions are aluminum, thermoplastic polyurethane (TPU), and acrylic foam. All three materials are lightweight and act as dampeners to the vibrations the club gives off at the striking point, making these clubs have a responsive feel to them that players want.

Progressive groove shaping

Spin Technology

In the longer irons (4-7), v-shaped grooves were milled into the face to create less spin for more distance and flight time. In the shorter irons (8-PW), u-shaped grooves were milled into the face for optimized spin for improved control and accuracy. In the wedges (GW-SW), tightly spaced u-shape grooves were milled for extra spin and precision around the green.

Progressive hosel length and shape

Hosel Length

The CG is lowered in the long irons (4-6) for extra launch and distance with those clubs. In the 7-9 irons, a slightly longer hosel promotes a bit less launch and lowers the CG some. The wedges have the longest hosel's, raising the CG up the most giving those clubs more accuracy than the other irons.
