I think i have seen more than enough people having problems with the flat serve of the Prince exo3 tour 100. So much so, that i think it may be worth discussing the only probable true weakness of this racket in order to find solutions. 1) Should one try to adjust ones technique for the flat serve compared to most frames? 2) Should one ad lead? 3) Should one resort to alternatives such as making spin serves, the main serves for this frame? On a personal note: I probably serve more aces with spin serves, than with flat ones. Especially on the 2nd serve up the T from the duece side or the wide one sliced to the forehand on the 1st.
