Fast spinny or slow spinny topspin

Hi Alois and Pingskills

i want to know what make the difference between a fast spinny topspin or slow spinny topspin, the movement, the speed of forearm, the place where the ball contact the racket, the technique, the angle of the racket, etc?

My coach dominate totally the parable of his loop, when he wants does a slow spinny topspin, to ensure the point if the ball coming hard, or a fast spinny topspin to win definitely the point, and i want to know,what i have to dominate to do this?

Thanks

Hi Cristh,

To get a faster spinny topspin are:
Contact for fast topspin is thicker and flatter
Swing becomes more forward rather than upwards
The bat moves through faster from start to finish position of your swing.
