Replacing a grip with a lighter one affects the swing weight how?

Replacing a grip with a lighter one results in a lighter swing weight. Swing weight is a measurement that reflects how the weight of a club is distributed and how heavy the club feels during a swing. When the grip is lighter, the overall weight of the club reduces, which in turn decreases the swing weight.

In this case, the lighter grip shifts the balance of the club, making it feel less heavy during the swing. As a result, the correct understanding is that replacing a grip with a lighter one directly affects the swing weight to become lighter, enhancing swing speed and potentially improving overall performance. The other options do not accurately reflect the physical principles of swing weight dynamics related to grip changes.
