Golf shaft elasticity and inflection point

Swing weight

　　Many ball friends on "Swing Weight" swing weight wondered, it refers to the position the Club level in swing weight instrument, measured between the head and shaft pulling weight. Swing weight to a A~E letters plus a 0~9 a number to represent, most ball friends using the C8 (light) to the D3 (re-) clubs. Using swing weight Club contribute to the feeling of the heavier ball, but research shows heavy swing weight can cause fatigue, not only physically less volatile when hit, and long-term use may cause injury, do not inadvertently! In addition when a different brand of hardcore group and wooden pole when you mix, be aware swing weight should try to keep it between the two units so as to avoid swing weight difference too many mistakes.

　　Elastic shaft and turn the crank

　　Rod body elastic "Flex" means ball Rod soft hardness, volume measuring method has by past using weights suspended Yu Rod body end of elastic test instrument, to more precision of Rod body vibration frequency interpretation, currently more to l (Rod body soft ballistic high), and a, (or m), and r, and s (or f), and and the x (Rod body hard ballistic flat), five level mark, but all brand on elastic range defined varies, purchase Shang be first understanding Rod body of elastic range and the ball friends actual swing Rod speed to judgment. In addition shaft twists and turns "kickpoint" different, will also produce different trajectory and feel. Inflection point means the ball bar perpendicular to the ground, by holding down the bottom shaft the bends, twists and turns the lower clubs called "pulling" feeling ballistic has a comparatively higher, while lower trajectory.
