IMO, in case of FH, the wrist extension/flexion are poison motions, because they just can open or close a racquet face. The wrist extension/flexion should be locked around contact. See also post #180 http://tt.tennis-warehouse.com/showt...=395364&page=9
Not with eastern grip. In my opinion, Federer uses wrist flexion in concert with forearm pronation in various combinations to vary contact point, rebound angle (side to side shot direction) and racquet-face angle (closing/opening). This is why his forehand has such incredible situational and positional versatility, disguise, and heavy spin with relatively flat swingpath, respectively.
