It seems that Yonex makes RD22 line just for Japanese players. I have searched the web and could only find info about them in Yonex Japanese website ( www.yonex.co.jp).
This line of racquet may be the most popular one in Japan because Yonex does not discontinue them like their other products. The first RD22 may have been made before 1997 because I saw one with the old Yonex logo. Then Yonex updated it almost anually 2000 (RD22 Long), 2002 (RD Ti 22), 2003 (RD Ti 22), 2004 (Ultimum RD Ti 22 type S). Anyone who have played or known something about these racquets, please share your opinions. Thank you.
