PLUS:
This is an extreme grip that puts a lot of action on the ball. The positioning of the wrist forces the racquet to whip up the back of the ball severely, generating tremendous topspin. You can hit the ball well above net level and it will still drop into the court. The resulting shot will usually have a high and explosive bounce, pushing your opponent behind the baseline. The strike zone is higher and farther out in front than all other forehand grips. The ability to handle high balls is what makes this grip so popular with clay-courters and juniors.

MINUS:
Low balls can be murder. That’s why professionals with this grip generally don’t do well on faster surfaces, where the ball stays low after the bounce. Also, you need tremendous racquet-head speed and wrist strength to generate adequate pace and spin. Otherwise, your shots will land short and your opponents can attack them. For some, it’s also difficult to flatten shots out, so putting balls away becomes a problem. And just as with the semi- Western, transitioning to net and hitting an effective first volley is a major challenge.
