I have a Blue Hammer a Black Hammer a red Pearl Hammer and a Burgundy Hammer
For me, the Blue Hammer was more versatile, and would generally crush the pocket, regardless of who used it. It was especially great in the hands of guys who could really rev the ball.
However, from my experiences, especially on heavy oil, the Burgundy Hammer hooked the most. The ball was inherently early, and gave you a good continuous read, all the way down the lane. My leadoff teammate in my Tuesday league still uses one today. He is a lefty, and he makes this ball look like new money! It still hits hard, and is the only ball that he brings to league to shoot with!
