I had one. I believe that the layout I put on it wasn't right for this ball. not knowing a great deal about it, I didn't ask ahead of time. I chose my favorite layout which is pin in middle finger for lefty or 5" pin-pap.
the ball seemed to labor no matter what surface prep I had. this ball would have been much better for me with a pin down and 4" pin-pap layout.
I feel like its a arson low flare like ball, but overall a bit stronger.
Pretty round shape, definitely acted like a symmetric piece
I ended up giving it to a JR at my center
I would email Mitch Beasley, he will tell you.
