The New AMF DECIMATE has a Hybrid cover and these covers tend to be very versatile. The DECIMATE core/cover combo creates a smooth earlier roll with a strong mid-lane motion that seems to work best on medium and medium heavy oil patterns. I drilled the ball with a 4 X 3 lay-out and the break point shape was arcing in nature on both the medium and the heavier patterns. The ball never displayed any over-under reaction when leaving the pattern, so if you’re looking for a go to ball this is the one.
