The straightest bowling ball that I have seen that bowls straight would be a plastic bowling ball. Plastic tends to not hook at all and these types of bowling balls for the most part is used for spare shooting since they bowl straight. A lower end hook bowling may be better because it can hook a little bit more than a plastic bowling ball. Below are some bowling ball that help you bowl straight.
