Yes, I know that weight in terms of balance point (head heavy, head light etc.) is a huge factor in terms of play-ability in a racket but how much does total weight factor in comparison? For example, does making a racket heavier give as much power as making a racket head-heavier? Same question vice-versa, what if you made a racket lighter? Would it give equal results if you made the racket head-lighter? Also, how MUCH lighter or heavier do you have to make a racket before you can actually feel it? For example, would you really be able to tell a difference in speed and power if you made your racket 2-3 grams heavier or lighter?
