Advantage and disadvantage of any type of serving

Hi sir Alois 

Why it is better to use pendulum, tomahawk, high toss service than a normal serving?

What is the advantage and disadvantage of this type of serving?

thank you

Hi Andray,

The main thing is that you are generating spin and so making it more difficult for your opponent to return the ball effectively.

Then as to which of these serves to use, depends on the serves that your opponent likes and dislikes.
