A high-performance bowling ball is usually made from Urethane or Poly Urethane materials.  Bowling balls are made using plastics, urethane, reactive resin, hybrid reactive, and particle (proactive). Plastics are usually for beginners with a smooth surface and offer the least friction and least hook potential, which gives you the entry-level performance bowling.  These are not high-performance balls, but even intermediate and advanced players use it but usually only as a spare ball. On the other hand, urethane balls yield a higher hook potential. High-performance bowling balls are usually made from coverstock and core made out of high-quality materials that use the latest technology based on research and development. These kinds of balls yield a higher hook potential. These balls is very effective in medium to heavy oil lanes.These balls are called medium reactive balls.
