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?
