I playtested the blue color,and I have since purchased a reel in white.
Why white? Tradition I guess. I don't care if people use brightly colored neon poly strings on their racquets, but it kind of annoys me on my racquet. I like mine to be simple and clean. It's got to be either white or "natural". Silver is pushing it.
Anyway, so far the white doesn't play any different than the blue version stocked by TW.
