Speed Double Twists
a high-speed swing, the golf club experiences centrifugal
force and gravities that cause two phases of twisting.
In other words, while the club head twists forward, it
also twists downward, as its result, except the position
of the club head at the instance of hit higher than the
originally set position, thus influences also in attenuating
the launch angle of the club head by 3° to 5°
that is an attenuated angle), and in an increase of back-spin
than the originally set, with a heightened trajectory.
As a result, the flight distance is shorter, and the ball
is still in a backspin during rolling after landing, making
the distance of rolling limited. Overall, the hit
distance is limited.
