Ebonite
The Ebonite Polaris is a solid reactive bowling ball with the Polaris core. RG 2.475 and differential 0.048 at 15 lb. For heavy oil. No longer made.
The new Polaris series from Ebonite uses a core body similar in shape to the great rolling Aero, but we’ve added a radial disc on the bottom of the ball to create extra motion. The great thing about having the disc on the bottom versus the top is that it never gets drilled into and maintains its purpose and integrity. We have tested the same core numbers with and without the disc and can see a pronounced increase in motion by using the extra piece on the bottom. The Polaris has an updated GSV-3 Solid cover, is finished with 1500 Siaair, and loves oil.
