Regardless of advertising hype there are balls that work better for specific styles and won't work as well for others. Example: After buying both the Labyrinth and Minotaur from Morich, and loving both, I bought a Collosus. This ball was horrible and I couldn't understand why until a friend told me it was a speed sensitive ball. Normally I am a "down and in" bowler with little hand and high speed, about 19mph, so this ball wouldn't work for me. I gave it to a friend with a pro shop and he sold it to an older gentleman with a slower speed who absolutely loved this ball.
