FWIW, I had 742 with it last night. Uncanny recovery, huge backend and unlike some other roto balls the pins don't "explode" as the ball enters the pocket. The Illusion keeps the pins really low. This ball behaves like a shiny solid, minus the early read. The reaction is hard to describe, you have to own one to know where I am coming from.
