I read on the board here that TW will, free of charge, try to match racquet specs if I purchased a pair of frames from them(same model of course). Well I ordered a pair of Volkl's from them last week and requested that they be matched as close as possible in weight and balance. When they arrived a few days ago the first thing I did was get my scale and balance board to see how close they were to each other. To my amazement they are only 0.6 grams different in weight and 1/10th centimeter different in balance! Job well done TW!!
