I don't buy that Copy of federer thing. his strokes remind me much more of haas than federer. esp. his FH which is a double bend FH and not a straight arm FH like federer is very similar to haas and his BH also. Look at the similarity: dimitrov: http://www.youtube.com/watch?v=ox97-DQdm00 haas: http://www.youtube.com/watch?v=N8wwXxPxzmA&feature=related Here is federer who looks quite different (FH especially) federer: http://www.youtube.com/watch?v=ESFU2IR_Dj0 People just say he looks like fed because he is a one hander (and they long for a new fed). but if one knows tennis he would see that dimitrov looks exactly like haas.
