My top pick for bowling balls is the Hammer Black Widow Pearl.  I stand about 5 to 7 boards off to the left of center and throw at the right gutter.  At the very end of my roll the Black Widow Pearl will break hard at the end.  I've rolled about 12 games with this ball and have 4 200 games at this point.  If you have questions about this ball I'll answer any you have if you leave a comment!
