Does anyone know what the three letter code signifies on Babolat rackets (or any rackets). The first letter seems to be the same for each Bab. model, the 2nd letter seems to vary a lot, and the third letter only varies between W X or Y. I have a PC MP 100" and I have found out that the MAY racket plays different from my other rackets that are MLX, MFW, and MCX. Also I found another MAY racket recently and it plays exactly the same as my other MAY racket?? So what do these letter mean??? Thanks again!
