Source sentences:
text: A stiffer shaft will not flex as much, which requires more power to bend and "whip" through the ball properly (which results in higher club speed at impact for more distance), while a more flexible shaft will whip with less power required for better distance on slower swings, but may torque and over-flex if swung with too much power causing the head not to be square, resulting in lower accuracy.
