I currently have an Extreme Pro (11.8 oz strung) and a reg Extreme (11.2 oz strung)--If I wanted to try and duplicate the feel and play of the Extreme Pro in terms of weight, how much lead tape could I add and at what points on the racquet? I was thinking about 10 & 2 or 9 & 3 posistions?? How much lead tape to add 0.5 oz?? Thanks
