I've got a couple of tour 100's 16x18 and recently have been playing around with lead. Started of with lead at 3 & 9 - 3g total. Result was stability but less access to spin on forehand and kick serve. Moved weights to 12 and added another 1.5g. Result was better spin on forehand and kicker and a slight increase in pace. Yesterday I added another 1.5g to 12 - now 6g total. Early days but the depth and spin on my forehand was fantastic. However, I had difficulty hitting my kick serve???:shock: I also noticed a definate 'slowness' in my ability to get to and hit volleys. When I made contact the shots were excellent but I was struggling against quick passing shots.
