Cobra are billing the King F6 irons as the ultimate progressive set and that because there are four types of construction from long irons through the speciality wedges.

The system is called TECFLO (Technology Enhanced Cavity Feel Launch Optimisation) and it combines multiple technologies and advanced constructions to optimise the performance of every iron.

In the 3-5 irons, a full hollow design with a face insert delivers a low CG and a highly responsive face for easier to hit, higher flying long irons. The 6-7 irons are a half-hollow design, providing a thin face with discretionary weight for optimal CG positioning and more precise irons shots.

They are aimed at the improving or part-time golfer that wants to hit better shots more easily and frequently and would like to hit the ball longer and straighter, from different strike locations across the face.

Down at address the Cobra King F6 irons boast a dark Nickel Chrome finish, which makes the white bottom score line on the face appear more prominent and helps align the face and frame the ball centrally. Traditional game improver design features like offset and thick top line feature, inspiring confidence before making a swing.

What becomes quickly apparent after a few swings is how easy the ball gets in the air, even on strikes slightly low on the clubface. This feature is combined with relatively low spin numbers (we experienced around the 5000 rpm average with the 30° 7-iron) leading to impressive carry distances in excess of 175 yards.

The consistency of the trajectory from each iron through the set is another redeeming feature, the full hollow construction of the long irons helping achieve a similar peak height to that of the under cut short irons, making control of distance more simple and predictable.

The specialty wedges are a versatile offering, unlike wedges that often appear as part of a game improver set, meaning golfers can be a little more creative with the shots that are required around the green. The muscleback construction also means they feel soft off the face.
