put lead tape back on my babolat PD last week, and now i can hammer serves and really hit the ball well..... do find it a challenge to keep the ball in... i was wondering what other people's experience is in lead taping a PD... i put the lead at 3 9 and 12 positions (and yes, i did want to move sweetspot down the racquet a little), and obviously the racquet is fairly head-heavy now. wondering if i have to go to moderate to heavy topsin on everything. or if i can get away with low flat shots. i do know i can not get away with lazy flat or lazy medium topspin (will just go long). anyone want to compare experiences??
