First off there is another pro that uses the K90 Julia Vankleno from the Ukraine on the WTA Tour. Also there are plenty of players using 90 sq.inch racquets. Off the top of my head Lleyton Hewitt uses a 90 sq.inch head size and all the players that use the Prestige Classic 600. Some of those Prestige Classic 600 players are Marat Safin, Gael Monfils, Agustin Calleri, Rainer Schuettler, Mariano Zabaleta, Mark Knowles, and Jose Acasuso.
