Hey guyz, i wonder if ya guyz can recceomend a string. Okay let me start, i juz strung a bg85 at 22 pound. And i think it is too weak, i mean i would like it to be able to hit harder, any reccomendation besides bg66/85 ? i uses a carbonex 20 (orignal) and MP100. Ohh yah i also wonder if this is possible, a mp100 with numbers for the date when it is created and the country, however it does not have a serial number. And at the back of the racket where the yonex sign is, there a CH and a numbers. I bought it in china. Is it fake ?
