Many racket manufacturers produce 2 versions of the same racket worldwide. They tend to supply the asian market with the lighter version whereas U.S. and Europe are supplied with the heavier version. For example, the U.S. version Wilson K95 weighs about 12.3 ouces when strung whereas the Asian version weighs only just over 11 ouces in strung weight.... Why must they do this??????? They feel that Asian players are weaker?????
