The Modified Tri-Core and Heat name are back and maybe better than ever. This is one of the strongest Heat balls to date with DR-7 Solid and a 2000 Siaair finish. This new Heat will provide plenty of hook for medium conditions and be a great addition to any bowler’s tournament arsenal while also providing a lot of value to anyone looking for a great mid-price ball.
