I've only owned two, the 3 dot and the Victory, both great balls for their respective eras.
The Victory is undoubtedly the strongest ball I've ever owned. It makes a great one-two punch with the Pro Purple. When the oil starts to carry down, and the Purple has trouble finishing strongly, just move a few boards to the left and throw the Victory on basically the same line. Works great!
