Golf clubs and many other ball striking devices may have various face and body features, as well as other characteristics, that can influence the use and performance of the device.  For example, users may wish to have improved impact properties, such as increased coefficient of restitution (COR) in the face and/or increased size of the area of greatest response or COR (also known as the “hot zone”) of the face.  The present devices and methods are provided to address at least some of these problems and other problems, and to provide advantages and aspects not provided by prior ball striking devices.  A full discussion of the features and advantages of the present invention is deferred to the following detailed description, which proceeds with reference to the accompanying drawings.
