The Affinity is the perfect addition to the Ebonite line up. Mine is drilled 65x4x70 with no hole. When comparing this to a Matrix, it is about 3 to 4 less overall, but with a more defined hook on the back of the lane. I wouldn't call it a flip, but a strong move that is very readable. When compared to the Game Breakers 2 Phenom Pearl, it is cleaner and more continuous. Which for me is perfect, my phenom pearl at times would read the friction too hard and quit just a little on the back. This ball will allow you to chase the pattern left as it breaks down. Add some surface and it blends the pattern even more. So far I prefer mine in the shiny state, this compliments the other balls in my arsenal well. I will drill more of this ball, I can see it being very useful on many patterns.
