If you know what balls you have had good experiences with in the past, it is possible to match up the core numbers and type of coverstock to try to match it pretty close. If you have not had many bowling balls, then the best thing to do is ask the people at your
Pro Shop and have them recommend a ball for you, or if you know what type of lane condition you want the ball for and the type of reaction you want compared to a ball you already have. For instance if you have a
Columbia rival and find that your lanes are a little too oily for it at the beginning of the night, then you will want the resurgence to match up with it, or if the rival is burning out you may want to go with a dead flush or momentum.
