I found one of those today, too. Felt really flexible and light ( I would say it had alloy, but what do I know?). It says graphite reinforced, red star mid, L4 4 1/2, and that's it, I guess. It was really cheap, but It would just be another racquet to occupy space on an already small bedroom. Besides, I'm not even a collector and the Matrix holds the place for "old-mid-to-swing-once-in-a-while-just-for-showing-off", not to mention the rok.
Anyway, what are the specs, just out of curiosity?
between Prince Michael Chang LB MP (27,5"), Prince O3 Red (27,75"), Wilson PS 6.1 Stretch (27,5"), Wilson Graphite Matrix and POG 110
