@Everybody :So the new strikes are from :
- Service ( Style = 1/2) => Sampras
- Forehand ( Style = 2/2) & Backhand ( Style = 2/2) => Federer
- 2-handed Backhand ( Style = 2/2) => Nadal (but it was made from 2 strikes during warmup)
I think the 2H-BH is the most well made anim coz it's the most fluid one, I'm pretty happy with the result, the other ones are correct as well, but not perfect, it's quite hard to reach a great result actually...

But I'm quite happy to see u like them..!
@Santiago92 :1/2 & 2/2 are the Style numbers in the Outfit Configuration screen, when u select the strike Styles.
@that_dood :use the "devmode = 1" in the Tennis.ini to change your strike styles in the World Tour without having to start a new game.
