What is an acceptable practice when a shaft has reusable old buildup tape already on it?

Using old buildup tape on a shaft can be an effective practice, provided that it will produce the desired grip size. When replacing or re-gripping a club, builders sometimes find that the existing buildup tape can still be serviceable. If the tape is intact and doesn't compromise the integrity of the grip or the feel, it can contribute to achieving the appropriate grip size for the player.

This approach can save time and resources while ensuring the player maintains a comfortable and effective grip on the club. It is essential to confirm that the old tape does not have any wear or damage that might affect performance. If it meets these criteria and satisfies the grip size requirements, then it is acceptable to use the existing tape.
