The best squash ball for club players is the Dunlop Competition Squash Ball. In chilly temperatures, more experienced players also utilize this ball. The ball has 10% extra bounce but is about the same size as the Dunlop Pro Squash ball. As a result, you have a little bit more time to play the ball and it is a little bit simpler to continue a rally. Before use, the Dunlop Competitive Squash Ball needs to be warmed up.
