any suggestion?? shoe(injuries,slow movement)- string(lack power)- grip(sweaty hands)- racket(prefer balanced-to a bit head heavy racket- about the racket,is it lighter the better coz after i try one lighter and heavier racket, i found out that lighter and flex racket can generate more power than heavier and stiff one, swing speed from lighter is much faster and the feel is better)~~~am i wrong coz i see many pro like stiff and head heavy racket
