I bought a CA bat which had Test and Plus stickers on it. (Can't remember which way round, but it was Plus on one side and Test on the other.) I don't doubt that it was an authentic CA 5000, the wood did look good and it responded well, was a fairly CA-like profile without much concaving at all, but the stickers were just applied wrongly. I think what CA may do is sell bats to these people at lower prices, since they are 'faulty', and maybe it's just a bother to correct them, who knows!
