What is the requirement for a player using a walking stick to deliver a bowl?

The requirement that the stick must have a broad base for stability is essential for players using a walking stick while delivering a bowl. Stability is crucial in bowls, especially during the delivery process, as it ensures that the player can maintain their balance while executing their shot. A walking stick with a broad base provides the necessary support, allowing the player to focus on their delivery without the risk of wobbling or falling over.

The other options present criteria that do not align with the regulations governing the use of walking sticks in bowls. Requiring the stick to always touch the ground doesn't account for different players' needs and doesn't enhance stability. Limiting the use of sticks to elderly players excludes individuals with disabilities or those requiring additional support, while specifying that the stick must be held in the non-dominant hand does not address the practical aspects of stability during the delivery process.
