What will be the result of replacing a grip with one that is heavier than the original?

Replacing a grip with one that is heavier than the original will lead to an increase in swing weight. Swing weight is a measure of how the weight of the club is distributed during the swing, particularly how heavy the club feels to the golfer. A heavier grip shifts the balance point of the club more toward the head, making the overall swing weight feel heavier. This change can affect the club's feel and performance during the swing, potentially altering a golfer's timing and control. Understanding swing weight is crucial for optimizing equipment, as it can influence a player’s comfort and ability to make consistent shots.
