Question: Are pressureless tennis balls as good as regular, pressurized balls?
Pressureless balls usually have a stiffer, woodier feel than pressurized balls, and except for the Tretorn brand, they're not quite as bouncy new. Unlike pressurized balls, though, they do not lose bounce over time. In fact, they get bouncier as they get lighter, due to fuzz loss. The balder they get, the more their flight, bounce, and spin response changes from what you'd expect of tennis balls.
