I'm using pro01, fh ju3 Asia h39 and I feel like something lacks when big hits maybe soft and slow. I want more deadly shots so pls reply me if u have experiences below rubbers which one is a better choice- big dipper h40, sanwei target national, 729 battle 2 or ju3 Asia h41. I don't want to use booster and don't know sanwei target national and battle 2 r how hard they r.
