According to Babolat, the Roddick Signature Racquet is supposed to have the same specs as Roddick's actual racquet. I just did some quick calculations, and discovered that it's not possible to add lead to a Pure Drive to make the weight, balance, and SW match up with the Roddick Signature stick. And I highly doubt that Roddick's Pure Drive has weight removed from the handle. So the Roddick Signature Racquet does not answer the question that we all used to wonder about. Does anyone out there know the REAL specs of Roddick's racquet?
