I bought an arsenal aggressive off ebay, buyer stated it was a 2nd due to a mismarked cg, no big deal my pro shop can find it. well i receive the ball and it has the track logo engraved in it twice with two different serial numbers on the ball, if I am correct this ball is not even legal to use in league play. also, how does track mark the cg on the ball, I couldn't find it on the website.
