According to what I have learned by researching golf balls, there are four kinds of balls, balls with shallow dimples, balls with deep dimples, balls that have wide dimples, and balls with narrow dimples. Shallow dimples make a ball have a lot of spin, causing the ball to have more lift , leaving the ball in the air longer, but when it lands it will not roll very far. The deep dimples cause the ball to have less spin, causing the ball to have a low trajectory, and roll much longer when it does hit the ground. Wide dimpled balls, give a ball long hang time. Small, narrow dimples cause a ball to go very straight causing you to have wonderful control in conditions such as wind.
A basic golf ball is made up of two layers, consisting of solid rubber, and a material called thermoplastic, or ionomer resin.
When a ball is hit it and flies into the air, a ball goes through two aerodynamic forces, which are lift and drag. The drag is created by the air, passing by the ball. Lift occurs when a ball is hit hard enough that the air pushes it upward into the sky. It is often mistakenly said that these two forces are created by the dimples on a ball. This is false. Dimples only make the forces greater or lesser effect of a ball. Dimples help a ball fly, because rather than a flat ball it carries with the wind.
With all this said, the less expensive balls may have less complex dimple structure, causing it to have less of an effect on the wind currents. More expensive balls may have more complicated dimples causing the ball to have more of an effect on the air currents. These differences may very well be the drastic difference in price.
