All of the companies have hot streaks. Back in the late 90's, you couldn't bowl a handicap league without seeing a Danger Zone or Violet 3D Offset on the rack. In early '06 there was a One, then Big One on just about every rack. In mid 05, it was the Absolute, in early 04 it was the Ultimate Inferno. In early 03, it was the Inferno.
I am going to list some other hot balls:
Columbia Chaos and Ti-Messenger
Track Triton Heat and Contender
Storm X Factor,Eraser and Trauma
Brunwsick Purple Monster
