1. A golf club head comprising:
- a club head body comprising a front end, a rear end opposite the front end, a toe end, a heel end opposite the toe end, and a sole; and
a weighting mechanism;
wherein;
the weighting mechanism comprises a first configuration and a second configuration;
the weighting mechanism comprises multiple weight ports and at least one weight;
the weighting mechanism comprises at least one weight mass differential;
the multiple weight ports are located only at the sole;
the multiple weight ports are arranged in a straight line and at an angle relative to a face plane of the golf club head such that the weighting mechanism toward the front end is closer to the heel end than to the toe end and such that the weighting mechanism toward the rear end is closer to the toe end than to the heel end relative to the weighting mechanism toward the front end, the angle being measured approximately parallel to a ground plane of the golf club head when the golf club head is at address;
each of the multiple weight ports is configured to receive the at least one weight;
when the weighting mechanism is configured in the first configuration and a user hits a golf ball with the golf club head in a predetermined manner, the golf ball breaks contact with the golf club head (i) with a first vertical spin rate, (ii) with a first horizontal spin rate, and (iii) with a first horizontal spin direction;
when the weighting mechanism is configured in the second configuration and the user hits the golf ball with the golf club head in the predetermined manner, the golf ball breaks contact with the golf club head (i) with a second vertical spin rate, (ii) with approximately the first horizontal spin rate; and
(iii) with approximately the first horizontal spin direction;
when the golf club head is at address, a vertical axis of rotational inertia extends vertically through a center of gravity of the golf club head;
when the weighting mechanism is configured in the first configuration, the golf club head comprises a first moment of inertia about the vertical axis of rotational inertia;
when the weighting mechanism is configured in the second configuration, the golf club head comprises a second moment of inertia about the vertical axis of rotational inertia; and
the second vertical spin rate is different than the first vertical spin rate, and the first moment of inertia is different than the second moment of inertia.
