Racquets designed for players just starting out in the game. If you're a beginner just starting out, you'll want a racquet that helps you return the ball with some power. Because you're developing technique and strokes, a racquet with a larger headsize will be forgiving when you don't hit the ball in the sweetspot (middle of the strings).
Ideally you won't want to go for a racquet that is too heavy either - this makes the racquet harder to swing and can effect your technique both on the preparation and follow-through. As a guide try to stick under 295 grams (unstrung) unless you're a very heavy build.
