10. A ball striking device comprising:
a head comprising:
a structural first component comprising a metal material; and
at least one non-structural second component comprising a non-metallic material;
wherein:
the structural first component and the at least one non-structural second component are connected to define a hollow center cavity;
wherein the structural first component further comprises:
a face located at a front of the head and having a ball striking surface configured to strike a golf ball, a top return extending rearward from the face, and a bottom return extending rearward from the face;
a band extending in a rearward direction from the face to define a periphery of the head;
the band further comprising a first end connected to a first side of the face, a second end extending from a second side of the face, opposite the first side, and a rear portion disposed between the first and second ends;
an arm extending across a bottom side of the head from the face to a central portion of the band;
the rear portion of the band further comprising at least two screw bases configured to secure one of at least two screw weights to the band;
wherein the rear portion of the band is positioned below a volumetric centerline of the head;
the band and the face define a first opening on a top side of the band;
the band, the face, and a first side of the arm define a second opening;
the band, the face, and a second side of the arm, opposite the first side, define a third opening;
wherein the at least one second component further comprises:
a top piece connected to the top side of the band and forming at least a portion of a top side of the head and configured to cover the first opening; and
a first bottom piece connected to a first portion of a bottom side of the band, forming a portion of the bottom side of the head, and configured to cover the second opening;
a second bottom piece connected to a portion of the bottom side of the band, forming a portion of the bottom side of the head, and configured to cover the third opening; and
wherein the first bottom piece and second bottom piece are separated by the arm.
