Frequently Asked Questions

Extra stiff flex shafts are built for golfers with the fastest of swing speeds. Typically very experienced players or professionals. Ideal for high clubhead speeds as they wont bend as much during the swing and will help those with fast swings maintain control over the ball.

Extra stiff irons have a reputation as being harder to hit than stiff or regular sets, and while this may be true for the majority of golfers, golfers who swing extremely quickly and will need extra stiff will find these shafts easier to hit than softer ones. It all depends on how quick you swing the club, and matching the haft flex up to work with your swing.

It all depends on what stock we've had traded in at the time but we always have some options for those faster swingers out there. They do sell quickly though so be sure to keep an eye out or drop one of our team a message if your desired extra stiff flex iron set isn't available.

Yes, you are able to get game improvement models in extra stiff flex. Many people believe if you need extra stiff flex you're automatically a good golfer, but in many cases there are golfers who may swing quickly but struggle to find the middle of the clubface.

As they are even stiffer than stiff flex, extra stiff bend very little during the golf swing, helping maintain a stable clubface through impact. This provides greater control, a lower ball flight and more consistent accuracy for fast swingers. Using the correct extra stiff flex shaft allows golfers to maximise distance while keeping their shots precise and predictable.
