Which club would be affected most by an ill-fitted lie angle?

The 9 iron would be most affected by an ill-fitted lie angle because shorter clubs, including the 9 iron, are generally more sensitive to changes in lie angle compared to longer clubs like the driver. A club's lie angle influences how the clubhead meets the ground during the swing. If a player's 9 iron is too upright or too flat, it can lead to significant misalignment and result in inconsistent ball contact.

With shorter clubs, the impact of an incorrect lie angle is magnified, as the player has less room for error in their swing. The shorter length and design of the 9 iron means that even small deviations can cause the toe or heel of the club to dig into the ground differently, influencing both accuracy and distance. For example, a too-upright lie can cause the player to consistently hit the ball left, whereas a too-flat lie can send the ball to the right.

In contrast, longer clubs like the driver or even the 7 iron have more length and allow for more margin in terms of swing path and impact position, making them less susceptible to lie angle variations. Thus, while all clubs benefit from a proper lie angle, the 9 iron stands out as being particularly affected due to its characteristics and
