There are some a bit different in contact points on swing, and hitting spots on ball :
● down-the-line to down-the-line
● down-the-line to cross-court
● down-the-line to in-side-out
● cross-court to down-the-line
● cross-court to cross-court
● cross-court to in-side-out
Do the shadow swings, observe by yourself, understand your own swing, and go out to the court to practice.
1HBH, right-handed, counter-puncher.
