Compared to the next in the series, the Wilson Roger Federer 21, this is 2 inches shorter at 19 inches and has a 1-point head-heavy balance to assist in putting enough power behind the ball. The light weight construction measures 175 grams with strings, the lowest in the set, making it easier to handle for aspiring junior players. In order to keep the weight low, the head size has been reduced as well to 80 inches in area.
