Tennis balls have a wide variety of acceptable
characteristics (felt, speed, and core) that
perform differently on different court. Most
premium tennis balls are sold in pressurized
extra duty, regular duty, and high altitude
versions, which represent the most common
mix of characteristics.
Here's more detail on the variations:
- As the name suggests, extra duty tennis balls
are constructed with felt that can withstand
better the abrasion of hitting a hard court
surface; however, an extra duty ball used
on a clay court will get too fluffy, so manufacturers
offer the regular duty balls as well.
- Although there are four speed categories
(slow, medium, fast, and high altitude),
most balls sold are medium, which meets most
of the requirements of both players and court
surfaces.
- Balls can be pressurized or not, but most
balls are pressurized. Once removed from
their pressurized container, these balls
lose their pressure in a few weeks, so keep
some unopened cans on hand.
