It is one of the cleanest materials we have ever produced. Made to get through the front of the lane much easier than previous materials.The solid version was chosen to give people a clean look through the front of the lane with predictability downlane instead of a clean and sideways motion like you would normally see.Purposely engineered for medium heavy to heavy oil.The Ellipse Asymmetric A.I. Core makes it more even rolling with more mass towards the center and less towards the poles.With great continuation, this is a great option for bowling centers with a lot of friction. We created this ball with some of the older lane panels in mind.
