x**i 发帖数: 113 | 1 Use continetal/backhand grip, toss the ball a little
backward comparing with flat serving, bend your waist a
little bit more, and concentrated on brushing the ball from

a combination of side spin and topspin, call kicker.
Flat serve can also add a little topsin, kind of hard to
descrip though... |
