A golf club head with an increased moment of inertia (MOI) about the X axis and the Z axis. Generally, the MOI about the Z axis is at least about 4400 g&#xb7;cmand the MOI about the X axis is at least about 2500 g&#xb7;cm. The radius of the bulge of the club face is increased while the radius of the roll is reduced to compensate for the gear effect produced by the increased MOIs. The bulge curvature is generally between about 0.016 cmand about 0.028 cm, and the roll curvature is between about 0.033 cmand about 0.066 cm. The roll curvature is greater than the bulge curvature.

Golf club head

A golf club head comprises a body and at least one self-extracting pressed weight assembly. The body comprises a face plate positioned at a forward portion of the golf club head, a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion of the golf club head and a skirt positioned around a periphery of the golf club head between the sole and the crown. The body defines an interior cavity. The weight assembly comprises at least three components and is configured for a press fit engagement with the golf club head. The assembly has a drive portion and a threaded portion.

Golf club head having movable weights

One embodiment of a golf club head having movable weights includes a body with a face plate positioned at a forward portion of the golf club head, a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion of the golf club head and a skirt positioned around a periphery of the golf club head between the sole and the crown. Two or more weight ports are formed in the body and at least two weights are configured to be retained at least partially within the weight ports.

A method is disclosed for matching a test golfer with a particular golf club selected from a group of golf clubs having a plurality of styles. The method utilizes data set derived in an initial procedure in which the club style preferences for each of a large number of pre-test golfers is recorded and correlated with a set of performance parameters for the golf swings of such pre-test golfers. This data enables the pre-test golfers to be classified into subgroups, in which golfers within the same subgroup generally prefer the same club style and golfers in different subgroups generally prefer different club styles. After this data set has been established, the test golfer takes a golf swing with a golf club, while performance parameters for the swing are measured. Based on the measured performance parameters and the previously established data set, the test golfer is classified according to swing type, and the optimum golf-club is then selected from the plurality of styles of golf clubs.

Method for matching a golfer with a particular club style

Embodiments of movable weights, such as weight assemblies and weight screws, for a golf club head are disclosed herein. One embodiment for a weight assembly, for example, comprises a mass element having a first end, a second end and a sidewall extending between the first end and the send end. The sidewall of the mass element defines a first bore extending through the mass element and at least a portion of the sidewall of mass element tapers in a direction from the first end to the second end. This embodiment further includes a retaining element configured to engage the first bore adjacent the first end of the mass element and defining a second bore. The weight assembly further includes an elongate fastener having a first end configured to be received within the second bore of the retaining element and a second end extending through the first bore and beyond the second end of the mass element when the mass element, retaining element and fastener are assembled together.

Movable weights for a golf club head

One embodiment of a golf club information system for representing a plurality of golf club head configurations includes a first member having thereon a graphic depicting a golf club head with openings and a second member movably coupled to the first member having marks thereon corresponding to a golf club head configuration associated with a predicted golf ball flight path. The first and second members are movable relative to each other to display some of the marks on the second member within the openings in the first member. The displayed marks convey golf club head configuration information.
