A ball striking device, such as a golf club, includes a head with a face having an outer surface configured for striking a ball, a body connected to the face, and a plurality of inserts connected to the outer surface of the body. The plurality of inserts are removable and interchangeable with other inserts, and at least one of the inserts has a weight that is greater than at least another one of the inserts. The inserts may be substantially identical in size and shape to enable the inserts to be interchanged with each other. Additionally, one or more of the inserts may be a primary insert with a secondary insert connected to the primary insert.
