Then with the King F8, they went all Nardo grey on us. Since the AMP Cell driver in 2012, Cobra has played around with bright colours on their driver heads.

Like all Cobra clubs these days, you can also verify your performance on the course by using the Cobra Connect sensor that is built into the grip and feeds data back to the free Cobra Connect app and Arccos Caddie service. The straighter face increased ball speed by another 1mph and I also preferred the slightly squarer look at address, so a win all round. As you are only moving 12g across 7cm, then the benefit is more from a change in balance, sound and feel from the different weight position.Ī better way to drop the spin is to reduce loft and I turned the hosel down -1° to 9.5° and took off around 200 rpm of spin. Moving the heavier weight to the front should have dropped the spin a little, but for me it was only fractionally lower and gave the same distance. Playing around with these adjustable options did improve performance. There is a red 14g steel weight that you can swap with the 2g black plastic version to move the CG back and forward a little. You can also adjust the launch conditions by swapping the weights on the sole. There is a good choice of head lofts at 9º, 10.5º and 12º and the new notation on the adjustable hosel shows the difference through the window as you vary it +/- 1.5º. The sound and feel of the King F9 driver was also a little better too and combined with a good selection of quality shafts you get a club that feels very poised and stable.

Combining this face with a faster head shape and a low CG position should do the business.Īnd so it proved, as when I tested it on GC2 against the previous King F8 with Titleist Pro V1x balls, I saw an increase in ball speed of 2mph. The Dual Roll design has an upper face with more curvature to give a higher launch with less spin, whereas the lower face has less curvature to do the opposite.Ĭobra’s faces have always been renowned for their forgiveness and the King F9 Speedback driver is no different. The face also continues the tilted bulge and roll axis that aligns with the high toe to low heel miss pattern that most golfers have. The King F9 face continues with the same circular Milled CNC pattern of the F8 that is more consistently thin from one head to the next than if it was finished manually. The King F9 crown now also features ‘Power Ridges’ that act as air tripping devices to smooth the airflow, so the whole package is quite a departure from what Cobra has done before. However 75% of the aerodynamic gain comes from the softer leading edges on the carbon crown that carries over from the previous King F8 driver. The Speedback design features sculpting around the sides of the head, where the yellow graphics are, to improve the airflow and it looks a bit like the back of a high performance motorbike. This does of course hurt the aerodynamics a little, but the gain in performance from the better CG position offsets this. However for a low CG you need to get the weight down, so the Speedback design combines this aero shape with a weight that protrudes from the sole at the back to lower the CG position. This high ‘tail’ is what improves the aerodynamics as it looks more like the shape of an aeroplane wing. In order to make the head go through the air quicker with less drag, they have softened the leading edges, made the crown a little flatter and moved the skirt or trailing edge of the driver upwards. Driver design tends to focus either on aerodynamics for club head speed or low CG for forgiveness, but Cobra claim that the King F9 Speedback driver can do both equally as well.
