I am looking for a good racquet for tennis elbow. I am a woman playing doubles most of the time and some singles. I do play with racquets that weigh around the 11oz. range. I have been looking at the Volkl line and the ProKennex line. The Volkl racquets have a 12 or 13 points head light is that too head light. They also have a flex of 60 or 61 The ProKennex Racquet Heritage Type R has a 57 flex with 4 points head light is that too head heavy? Some ProKennex have a high flex number. Very confused about numbers...... HELP!!!!!!
