1. A golf club comprising:
- a shaft; and
a golf club head comprising;
a face component;
a body comprising a composite crown, a metal sole, a heel side, a toe side, a hollow interior, and a rear side;
a center of gravity,a mass M,at least one hollow tube extending through the hollow interior from the sole to the crown;
at least one cushion composed of a polymeric material, anda first electronic diagnostic insert sized to fit within the hollow tube,wherein the first electronic diagnostic insert comprises a protective shell, a plurality of sensors, a removable memory card, a first, high density end comprising a first material, a second, low density end comprising a second material having a lower density than the first material, a length L, and a mass MT,wherein the at least one cushion is disposed within the tube between the first electronic diagnostic insert and the body,wherein the first electronic diagnostic insert records data about a golfer'"'"'s swing when a golfer swings the golf club,wherein the memory card is configured to store the data,wherein changing the orientation of the first electronic diagnostic insert within the tube changes the location of the golf club head'"'"'s center of gravity along a vertical Z axis,wherein the distance from the midpoint of the length L to a center of gravity of the first electronic diagnostic insert when the first electronic diagnostic insert is disposed within the tube such that the high density end is closer to the sole is defined as 1/2D,wherein the golf club head satisfies the equation D≧
0.065(1+M/MT), andwherein D is a total center of gravity distance change for the first electronic diagnostic insert when its orientation is changed within the tube by being flipped.
