I was stuck between the World Class and the Big Bang. I ended up with the Big Bang just becuase I wanted to open the lane up a little more. I have never been able to throw anything with surface.... I usually have all of my stuff polished.
Anyway, the pro shop guy told me to throw it out of box surface, and go from there. Well, it was unbelievable. The ball read the midlane so well, and then when it got to the backend, it was all I could ask for. I have it drilled stacked.
I have been bowling 2 weeks with this ball... 777, 684... (now, if I could only pick up a 7 pin)
