The final stage of any development is the dimple design. Once the ball development is complete, and the spin rates of the balls are known, then the aerodynamics are created to help control the flight. We vary the dimple sizes, depths, edge angles and shapes around the ball to control the lift and drag coefficients on the ball. Too much lift will create ballooning and shoot up into the sky and be short, while too much drag will make the ball fall out of the sky. So controlling the two will create the best carry and roll and maximize distance. The numbers of dimples don’t really control the ball flight, but most balls today run between 300 and 400 dimples.
