Hello everyone! I'm using the Babolat Pure Storm LTD bumblebee-black-and-yellow-2008 version. I was playing fine with the racquet in its stock form, but today I'd a hard time to return my friend who is using the volkl pro c10 black-2008 version. My backhand, slice, and especially forehand were being push-back, and it was very frustrating. I believe it is time for me to start putting lead on my racquet. I want to ask you guys, especially ones who had lead the PSL, about some tips to lead my racquet such as how much weight should I put on, where, and etc. I'm 5'4 guy, and I'm satisfy with the racquet's swing-weight. I want the racquet to be more solid and more stable. I've no experience whatsoever with leading, so please help me!
