2. Urethane Bowling Balls Designed for much hook. Drags across lane providing less friction and more speed.

3. Resin Bowling Balls Does not drag across lane because of increased friction so it travels slower. Much friction on surface and lane which creates most hook.

4. Particle Bowling Balls A resin ball with glass pieces added to create more grit, to help it grip to the lane. Most PBA bowlers prefer a particle ball because hook is easiest to control.

5. Polyester Bowling Balls The most common type of bowling and the cheapest to manufacture. Polyester is plastic. They last the longest. Polyester bowling balls are hardest to control.
