When sourcing cricket tennis balls, you must prioritize weight, bounce, and felt quality. For standard play, the weight should typically range between 70g to 85g. Ensure the internal pressure is consistent to provide a bounce height of 120cm to 140cm when dropped from a height of 250cm. The outer material should be a high-grade needle-punched felt or a wool-nylon blend to ensure durability against abrasive concrete or asphalt pitches. Additionally, look for deep-seam technology which mimics the grip and swing characteristics of a leather cricket ball.
