Flex Selection
Flex refers to the amount of bend that a shaft has. A more flexible shaft will help the club "whip" through the ball, creating greater clubhead speed and more distance. This works well for golfers with slower swing speeds. Golfers that swing the club hard and fast will lose accuracy if the shaft is too flexible and should get a stiffer shaft
To determine what is best for you, look at the chart below
Woods
| Driver Carry Distance (How far the ball goes in the air, not including the roll) | Shaft Flex |
| 250+ yards | Stiff |
| 210 - 250 yards | Regular |
| 180 - 210 yards | Senior |
| Less than 180 yards | Lady |
Irons
| 5 Iron Carry Distance(How far the ball goes in the air, not including the roll) | Shaft Flex |
| 170+ yards | Stiff |
| 150 - 170 yards | Regular |
| 135 - 150 yards | Senior |
| Less than 135 yards | Lady |
If your distance falls right at the cut-off for one flex or the other you have two options.
1)If you are looking for more distance go with the more flexible shaft.
2)If you are looking for more control go with the stiffer shaft.
