Composite: Offers superior touch and softness. The best for competition. Polyurethane: Provides a soft touch, with durability and water-resistance. For practice or match play. PVC: Durable and scuff/water-resistant, but not as soft as polyurethane. For practice and recreation. Rubber: Waterproof and the most durable, especially on asphalt. Great for institutional use. Felt/Suede: The softest, friendliest cover material. Exclusively for indoor use.
C-2: The best touch and rebound, but with improved air-retention due to its mix of carbon and latex. Latex: Offers superior touch and rebound. Least air-retention quality; requires more frequent filling. Butyl/Rubber: Retains air exceptionally well and provides uniform pressure dispersion.
