What is the difference between reactive resin and urethane bowling balls?

Reactive resin and urethane bowling balls differ in their composition and performance characteristics. Reactive resin balls feature a reactive resin coverstock that enhances hook potential and provides stronger backend reaction on the lane, resulting in increased pin action. This coverstock offers better traction on oily lane conditions, allowing the ball to grip the surface and achieve a strong angular motion. On the other hand, urethane bowling balls have a urethane coverstock, which generates less hook potential but offers excellent control and consistency. Urethane balls are ideal for dry to medium-dry lane conditions as they create a smooth and predictable roll with limited backend reaction. This makes urethane balls popular among bowlers who prefer a more straightforward and accurate shot. Each type has its advantages, so selecting the right ball depends on individual preference and lane conditions.
