Does TTD have the feature to save or highlight certain posts? So I can easily find and review some of the good tips.
I have been practicing watching the server's motions, following the ball's trajectory and syncing my body with its rhythm. I think I am making a little progress, although I am very not used to it. There are so many things to look at, and I once forgot to return the ball lol.
And I have to say most people don't work on service enough - we are hobby players after all. I don't have much insight into the service tactics. But most people (up to ~2100 USATT) are lacking variation and deception. A few players (1300 - 1800) actually have better serves that give them advantages for 3rd ball attack.
