Hi, After playing with the Babolat PureDrive GT for over a year, I want something heavier so I bought some lead tape. As the PD Roddick is a playersstick where there are good reviews on, I want to upgrade my current PD GT (not the new 2012 version, but the version before that) to the specs of the PDR. Have someone already upgraded/customized their Babolat Pure drive GT to an PD Roddick model? Where dit you put the leadstrips on the racket? Stiffness and length will be the same. And furthermore: what are the experiences with playing with a customized Babolat Pure Drive, can someone tell if you feel the difference with a fabric PDR? Makes a stiffness of 2 such a difference? I have searched on this forum and Internet but could not find suitable info on this topic... Hope someone can help me out!
