Golf is a competition where you can choose the ball yourself
Hello everyone. I’m Ogura, the evangelist of golf.
This time I will talk about how to choose a golf ball.
Golf is a rare sport in which you can choose the ball to use for the competition from many models with different performances. Think about it, baseball, soccer, volleyball, basketball, tennis, table tennis, you use the same ball as your opponent when you play, right? Golf is different. You can use the one that suits you from the many types of balls. It may be the closest to bowling playing with my ball.
Golf balls are sold in shops and courses just like clubs. New golf balls are generally sold for 150-800 yen each.
The price difference is quite wide, with low-priced items at around 150-400 yen and high-priced items at 600-800 yen. Like clubs, there are also used balls, which are sold under the name “Lost Balls”. It depends on the condition, but the cheap one is 100 yen or less per ball, and the expensive one is about 400 yen per ball, and in most cases it is a pack of 1 dozen or 20 to 30 balls. Even if you buy a pack of 30 balls, it’s a little less than 2,000 yen, which is cheaper than a new one, so I think it’s okay when you’re a “super beginner”, and it’s enough if you just want to enjoy playing for the time being.
However, if you want to pursue a good distance and a good score, you also want to stick to the ball. The way you fly depends on the type and characteristics of the ball, and controlling it is the true way to enjoy golf.
Golf balls are roughly divided into “3 types”
Golf balls can be broadly divided into three types.
・ Distance system
・ Spin system
The distance system is a ball that mainly pursues flight distance performance, the spin system is a ball that mainly pursues spin performance, and the middle is called the “third ball”. The reason for the “third” is that golf balls have long been developed and manufactured in two types, distance type and spin type, but in recent years the technology has developed and the ball has the best distance and spin. Has come to be able to be made. Therefore, it is called the third ball because it is the third category.
The flight distance and height of the ball can be determined by changing the club. However, the performance of the ball is very important for finer control from there. Even if you hit with the same club, the flight distance will change if the height of the trajectory changes depending on the type of ball. Even if it hits the same place, the amount of rolling from there will change.
Therefore, golf balls are packed with many technologies and ideas to achieve the desired performance. The ideal of a golf ball is that “a driver does not fly and bend, and an iron or wedge stops perfectly.” In order to get closer to that ideal, the makers of balls are conducting research every day.
I will explain the structure of the golf ball
The structure of golf balls varies by type, but most balls are multi-layered. The main component is rubber, but recently, in order to pursue performance, there are balls made of synthetic resin such as ionomer. Performance will differ depending on the number of layers and materials.
Let’s briefly explain how the ball works.
The multi-layered part is easy to explain if the ball is sliced, so I will explain using the sliced model.
The two balls are of the same brand, but have different numbers of layers due to different performance goals.
It’s a little confusing, but the “Srixon Z-STAR” on the left has an exterior called a “cover” with the outermost dimples (the bumps on the surface of the ball), one layer just inside, and a gray layer inside. It has a three-layer structure. A three-layered ball is called a three-piece ball.
The “Srixon Z-STAR XV” on the right is called a 4-piece ball because it has a four-layer structure consisting of an outer layer, one layer immediately inside, a pink layer inside, and a blue layer in the center.
The reason for this multi-layered structure is that the ball is struck by the face of the club at the moment of impact and collapses. At this time, the degree of crushing of the ball changes depending on how much collision energy (head speed) and how much loft angle (slightly different from the loft angle of the club when swinging) hits the face, and it is exhibited by the crushing condition. Performance changes.
Simply put, when a driver with a fast head speed and a loft close to vertical impacts, the ball is crushed greatly and energy reaches the innermost layer, making it easier to demonstrate the performance of that layer. On the other hand, if you make an impact with a short iron with a slow head speed and a large loft, the collision energy will be smaller due to the slower head speed, and since there is a loft angle, the impact will be like rubbing the ball, so the crushing of the ball will be small. The shallow layer reacts, and the performance of that layer is more likely to be exhibited. (It’s not easy at all … Sumimasen)
In other words, by increasing the number of layers inside the ball, it is possible to separate the layers that react according to the head speed, and the more layers there are, the higher the performance of the ball.
