Ok, I recently bought two Yonex RDiS 100 MP rackets. I like them, but they're very light, particularly head light I think. I've never used lead before, but would this be a good way to make the racket feel more "solid"? It kind of feels like it gets pushed around a bit against bigger hitters, and balls tend to fly a lot on me. I'm particularly interested in making the racket feel more solid on both serves and volleys. Does lead at 3 and 9 o'clock do this? How much lead? Where do you buy lead? Can you just stick it on? If you stick it on and it's no good, can you just take it off and move it? Pros and cons of lead? Should I just have bought a heavier racket to begin with? Anyone had any experience leading up the RDiS 100 MP? Thanks!
