I tried to throw my Big Deal in box finish and I absolutely hated the ball. Rolled too early, quit half way to the pin deck, and hit weakly. I was about to give up on it and then I hit it with 800 grit polish and the ball came alive. It saved energy but still would turn a corner and the hit/mix factor increased greatly. Do not be afraid to polish up the Big Deal.
I would agree with Wallshot that the Black Widow seems to perform better in box or matte condition. When I polished it up, I really did not like the look I got out of it.
