I've had two Strike Zones, and I threw them at every surface prep imaginable. At 2000 smooth, it was cleaner in front and had a harder arc in back. Polished, it was much pushier, and significantly sharper at the break.
Also, IME, a polished Strike Zone isn't quite a Red Zone. At one time I had both balls drilled identically (5" under by 60 degrees, XH on PAP), and with both polished, the Strike Zone was a few feet longer and somewhat stronger at the break.
