How to choose a new club
Choose according to the weight and length of the club: you should try to choose a longer and heavier club within the range that you can easily swing. According to statistics from foreign countries (Japan), for ordinary golfers: length is 45 inches, weight is between 295-300 grams; length is 44 inches, weight is 315-320 grams is more suitable. It can also be selected according to the head speed: 290 grams for 40 meters/second (90 miles per hour); 305 grams for 43-45 meters per second (95-100 miles per hour); 46 meters/second or more. Choose 320 grams.
Choose according to the weight of the swing: we can often see the words C9 or D0 from the club, which is the swing weight, which is used to indicate the action of the club head. According to the weight feeling of the swing, it is divided into five stages of ABCDE from light to heavy. In these five stages, it is divided into 0-9 grades for every 1/20 ounce (about 1.42 grams). Generally speaking, from C4-C9 to ordinary women and weaker men, D0-D3 is an ordinary male, and D4-D8 is used for general occupation (or strong) players. I hope everyone notices that this value is a relative value, not an absolute planting. Even if the club has the same weight, if the length is different, the weight will be different, such as 44 inches and 45 inches. The ball is supported, the balance of the swing is D0, and the 44-inch swing is more heavy. I hope that everyone can remember the swing weight of the driver that they are using now. When you pick a new kicker, you will lose a lot of detours.
According to the weight of the shaft to choose: the main basis for selection is the swing rhythm and head speed, presumably many high-level players will have experience: using the shaft suitable for their swing rhythm and speed, the distance of the ball It will increase; in general: players with fast swings prefer to use a heavier shaft because the heavier shaft is more stable when the ball is hit. Reference data: a golfer with a head speed of about 40 m/s, a suitable weight of 50 g before and after; a club head with a head speed of 43-45 m/s is suitable for a weight of 60-65 g; 46 More than m/s is suitable for 65-70 grams.
According to the hardness of the shaft: softness means the elasticity of the shaft. It plays a very important role in the stability of the ballistics and the flight distance of the ball. Generally speaking, the harder the shaft is, the more stable the ballistic path is; the softer the distance is, the farther it is. There are five specifications: Ladies; Amateur; R (Regular); Hard S (Stiff); Super-Stiff. The hardness of the shaft should be determined according to the speed of the swing: 75 mph (34 m / s) or less: hardness L; 75-85 mph (38 m / s): A or R; 85-95 Miles per hour (43 m/s): R or S; 95-108 mph (48 m/s): S or X; 108 mph/s or more: X or XX; Please note: R of each brand The hardness standards of S and X are different. It is necessary to fully combine their own swing rhythm to select.
According to the torque of the shaft, the steering change generated when the shaft is stressed is the torque, which is referred to as TQ. For players with slower swing speed and insufficient strength, the torque should be chosen to be above 5.0. When the shaft with larger torque is hitting the ball, the face is easier to turn over and there will be more obvious “pumping”. Feel the swing more smoothly. For players with a fast swing speed, the torque should be chosen below 4.0, because too much torque means that the shaft rotates too much and it is difficult to control the flight direction of the ball. However, if the torque is too small, the lifting (touching) of the shaft will be too sensitive. When the swing is very hard, the rhythm is not easy to master. Not only will there be a loss in distance, but it will also be easier to produce a right-handed ball (because the ball The left side is rotated less).
It is selected according to the bending point of the shaft: the bending point of the shaft is the portion where the bending is greatest when the shaft is bent. The shaft is generally divided into: high (HP, near the grip side), medium (MP, opposite middle), low (LP, near the head side) bending point. It mainly affects the height of the ballistics and the speed of the head. A more vivid example is the role of the joints (squats, knees, ankles) of the legs when we play. The ball with high bending point has a low ballistic trajectory and good accuracy; while the low bending point has a higher ballistic trajectory and a farther distance; the choice of which bending point should be based on the player’s individual needs. Generally speaking, players with low and medium handicap apply high and medium bending points, and players with high and medium handicap are suitable for shafts with medium and low bending points.
If the club is too light, it is easy for the player to use the strength of the arm to swing the club too much, and it will not generate enough centrifugal force to fully exert the strength of the body. The longer the use time, the lower the head speed. In addition, if the club is too light, the swing will be unstable and the effective hit rate will be reduced. The trajectory of the ball that is hit by a heavier club will be more stable, but if it is too heavy, the player will forcefully grasp the club when it is on the pole, thus violating the basic requirements of the “do not force” swing. It is impossible to maximize the swing speed at the moment of hitting the ball, and the distance will definitely suffer.
