Solid-core balls, particularly the Titleist Pro V1, may be sending the traditional wound balls on their way to the museums where wooden shafts now reside. Solid-core balls don't have rubber bands. What the golf ball lacks in size it makes up in scientific complexity. Take golf-ball dimples, for example. The number and depth of the dimples play a big role in determining ball flight.
Dimple depth is measured in thousandths of an inch.
No ball in any sport is the subject of as much fierce hype and salesmanship as the golf ball. Tour pros obviously want every edge possible. About 48 million dozen balls are sold in the U.S. each year. The new balls are delivering. Nine of the first 11 tournaments this year were won by golfers using the Pro V1.
