Hi! I am planning on buying a VTZF 4u. I currently use a arcSaber zs 4u g5. I had to put 3 over grips on it before the racket felt comfortable for me. I feel that this has changed the balance the of the racket and my smashes are poorer as a result (just a feeling). As I am looking through buying options, it seems g5 is more available than a g4. I am concerned that I will have to put 3 over grips again and it will change the head heavy nature of this racket esp since I am planning to get 4u (mostly play doubles hence 4u). I would like to get your opinions on g4 vs g5. What do you think I should do?
