It appears there are two hard court balls that really stand out among the pack. The Wilson US Open balls are consistent, durable and yet don't feel like rocks like some of the less expensive brands. But for everything the US Open balls do, I really think the Penn ATP balls do it just a little bit better especially the bright yellow color of the Penn's.
The only tennis ball I use for more than 2 sets. If your courts are clean this ball last forever.
These tennis balls last 3 times longer and keep there pressure and bounce longer than all others. Worth a bit extra to buy. Great for all hitters including big hitters!
We have used these for our last three tournaments and they have performed maginificantly. Hold up through 3 sets of big hitting. Maintain pressure and bounce with no excess fluff.
