Koyo, hope you can give some advice on the Yonex MP55. Just read on here that you have your own retail racquet store. Your the person to ask about racquets. Is the MP55 really an Iso800 replacement? Are the Iso800 and MP55 that similar? Thanks in advance.
Dear Ah Ching, MP 55 is not the replacement for iso 800. If you are looking for a racquet to replace 800, I think ti 10 regular is the one that is closest to a replacement, because they are both stiff and head heavy racquet. Any further questions, please email me : koyoho@msn.com. Thank you. Koyo
