I'm trying to purchase a new racquet and read there are many fake YY racquets on the market. That's why I would like to understand more about the racquets. Can anyone tell me what does the SP code on the shaft means (see attached link to picture, the SP code is above the engraved code 7170).
I was browsing the forum and saw a lot of discussion about the different codes, but none specifically mention about this one. Most discussion is on the SP/JP/TW code after the serial number. That's why I would like to know if this is the SP code everyone is referring to. Thanks in advance!!
