Ball striking devices, such as golf club heads, include devices within andor otherwise engaged with the ball striking head that allow users to selectively change the sound andor other aspects of the \u201cfeel\u201d associated with using the ball striking device to strike a ball. In one embodiment, a caul for applying pressure in laminating includes a base portion positioned between first and second corner portions. A mobile terminal receiving a differential BSPM updates the flows with the information contained within the differential BSPM or adds the information contained within the differential BSPM for a new flow. Unique configuration data is provided to each data concentrator for its unique sensor type complement.
