Differences and problems discovered with my Wilson K Factor K Pro Staff 88 (Pete Sampras Signature series edition) tennis racquet. I found problems with the differences in weight balance and bad paint work showing lack of QC standards.

These images shows a more "balanced" replacement after Royal Sporting House Singapore replaced my earlier model. The new model has the embossed RED "W" Wilson logo on the strings and plastic wrap on the grip. The new Wilson K Pro Staff 88 now seems to be close to the original balance of my first Wilson K Pro Staff 88 purchased at an earlier date but still not "exactly" identical
