What does making a racquet more head light do? And how head light should I make it? I want to add some to 3 & 9 but also put a bunch on the handle to make it about 10 or so points head light. How much should I put at 3/9 and the handle? Same with a Prince More Control DB800? I want to put some at 3/9 and make it about 10 points head light. Where and how much? Thanks a bunch to anyone who can help.
