AS I already stated, I am only curious. I recently purchased a HYpe urethane and while I don't often like some of the more exaggerated colors (Intense Inferno, New Breeds, etc), I find the all black ball to almost lack a visual personality. I guess I've gotten used to some beautiful, phased color patterns: reds, silvers, greens, and multi-blues. Some of these balls are just so beautiful to look at.
On the flip side, I often do best with the ugliest balls.
I don't want to get into any arguments or discussions. Beauty is in the eye of the beholder after all. I wondered how many black balls were currently available. I also wonder how many of them will sit there, unbought, solely because people don't like the way they look. That's a question that may never be answered. Color has nothing to do with my ball choices, personally. Like most bowlers, a good ball is one that performs in the niche I need filled.
I do admit that there are balls I could just put on display only to admire.
