Cobra F6 Driver Review

While all good golfing brands aim to improve on their designs, with each new release, Cobra continues to be right at the forefront of the pack when it comes to innovation. Nowhere is this more evident than their metal woods. Earlier in the year, they expanded the King LTD range, by incorporating two new drivers; the F6 and the F6+ varieties. The new sticks all come with state of the art adjustable weighting so that handling is better than ever before.

This review of the brand new Cobra F6 driver will take a closer look at some of its key benefits and discuss any relevant weaknesses.

What Cobra Says

As is usual for a product release, Cobra issued a brief statement on the main features of the F6 driver. They called it their ‘most forgiving adjustable driver ever’ and pointed out the CG tuning and weight system that stretches from front to back. It is this clever weight balance that enables players to increase their distance by fine-tuning their spin and launch characteristics.

Getting to Grips with the Technology

E9 Forged Face

The patented E9 technology has been highly sought after for many years and it has made Cobra a household name. The manufacturer has been careful not to deviate from the features that fans of the brand really love and this is no different in the case of the F6. The E9 forged face has been made slightly thinner, so that the surface keeps more of the ball speed away from the middle. However, this is the only real change.

Adjustable Weight System

In 2015, Cobra gave golf fans the rather clever ‘Flip Zone’ weight adjustment system. However, it wasn’t rolled out across the whole range; they kept it limited to just the Fly-Z sticks. So, it should come as a nice surprise to find that the feature has now been added to both the F6 and the F6+ varieties. Ultimately, the weight system on the F6 driver is much the same as the early version, but some of the minor problems have been ironed out.

The choices are very simple. The weight option can either be set to straight ahead and a lower flight path and spin or it can be brought back to the rear of the driver. This intensifies the spin and launch force, while also keeping the ball more stable as it leaves the ground. The F6+ offers those with an eye for detail just a little bit more control, but unless you’re really scrutinising your game, the difference between the F6 and the F6+ is not too prominent.

Speed Channel

The Speed Channel is another feature that is already well known (it was launched in 2015), but it is worthy of a revisit because Cobra is the only company to be making anything of the kind. The Speed Channel is a narrow gap that surrounds the perimeter of the driver’s face, at the point where it merges with the crown. It is valuable because it allows Cobra to experiment with the width of the face without compromising on ball speed retention. In short, it leads to more viable ‘misses’ and it is a highly functional aspect of the F6 driver.

Appearance and Visual Features

First things first; you couldn’t mistake this driver for anything but what it is. Cobra sticks have a distinct look and connoisseurs recognise it from a mile away. The F6 has the characteristic head, with its elongated ‘pear shaped’ curve. As usual, the depth of the face sits somewhere close to the centre. It couldn’t accurately be called shallow or deep, so it provides a satisfying balance for those who like it that way. As the head is visually expanded by that elongated curve, this driver is bound to please those who appreciate a good visual boost on the green.

As for the different colours available, fans of the brand will be pleased to know that, while there are a number of options, the range remains sensibly small. Cobra appears to be sticking to the shades that it knows are popular, so that means black, white, blue, and orange. There isn’t much to shout about when it comes to the face, but the sole of the driver is one of the finest looking that Cobra has produced in some time. It is sleek, chic, and a really elegant piece to take out on the green.


The F6+ has been the subject of minor criticism for how loud it becomes when it makes contact. For reasons that aren’t entirely clear, the F6 doesn’t really share this problem. It is noticeably quieter, in most circumstances, and most closely resembles the BioCell and Fly-Z varieties. When it strikes, it produces a pleasant noise, with only a little of that clanking, clinking metallic ding that Cobra has been known for in the past.

When it comes to handling and feel, the F6 driver demonstrates a remarkable degree of control and stability. This is primarily because of the shape of the head and MOI of the design. The driver is particularly effective when it comes to balls struck laterally across the face. It doesn’t exhibit any of the jerking and warping problems that many of the less sophisticated sticks do. Then again, it is important to point out that centre hits and misses aren’t as effortlessly discerned with the new Cobra F6 driver.


When reviewing the F6 driver, there has to be a decent amount of focus given to the impact of the weight adjustment system. For the most part, the head sits distinctly within the low to mid sphere of spin. It produces what, for all intents and purposes, is a higher ball flight. Careful readings from driving range data show that the weighted system does have an impact on both launch and spin. This is most prominent when the weight is transferred from the front of the stick to the back.

Ultimately, the degree of impact will be different for everybody. It, of course, depends on how you play and how effective your strikes are. Nevertheless, Cobra claims that the difference in spin can be as large as 600RPM. The average though is substantially smaller, at around 400RPM. This was a consequence of transferring the weight from front to back, as described. The adjustment also expanded the launch by approximately 1.5°, which could be a real boon for those trying to diversify their game.


The Cobra F6 driver is able to give out some real distance, due to the shape of its head. Once again, the exact amount of distance gained (on a less sophisticated stick) will depend on a whole litany of factors. However, in skilled hands, the driver is consistently impressive. It knocks its predecessor, the Fly-Z driver, out of the park. It has, on average, around 1.5MPH more speed.

On lateral misses, an estimated ten yards of carry and 3MPH ball speed drop were observed. If users transfer the weight forward, low misses vertically on the face are enhanced. Alternatively, if you do it the other way around and push the weight back and low, it is the lateral misses that are enhanced instead.

The Bottom Line

Major Pros

The Cobra F6 is, in many ways, a true workhorse of the green. It is sturdy, reliable, and guaranteed to put in a solid performance, even on the bad days. Misses are a rarity and don’t feel like much of a problem at all because that innovative speed channel is waiting in the wings to save scuppered shots.

The driver is lightweight, but it doesn’t compromise on durability. That sense of weightiness and heft is really important for high-quality strikes, but you don’t want to feel like you’re dragging an unwieldy club through the air either. Fortunately, the F6 driver provides optimum balance with its clever weight adjustment system, which is easy to use and very effective.

Major Cons

It is worth point out that for some players, the F6 driver might still feel a little too light in the hands. The head may also feel too large, even its aesthetic is bulkier than its handling and strike. This feature could, essentially, go one of two ways. Some players will appreciate that fullness and roundness, because it ups their confidence, while others will wish the head was slimmer and sleeker.

A Final Word

The Cobra King F6 is an all-around great driver. It is difficult to argue with its cutting edge weight adjustment system or its carefully shaped head and face. Overall, it provides enough forgiveness for high handicappers to get plenty of satisfaction. But, it also offers lots of fun and interest for slightly more serious players too, which is no mean feat. In many ways, it is a nicely rounded merger of the Z+ and the Fly-Z, but this doesn’t mean that it isn’t worth a little time and investment.
