If you're just starting out, you can certainly rent a racquet at many facilities, but you'll be better off buying one of your own. Racquets come in many shapes and sizes. Most are variations on the oversized-head type. Those racquets are light and strong and more powerful than slimmer-bodied models. Their streamlined heads and broad dimensions guarantee better maneuverability and stiffness. When buying a new racquet, choose one that feels right for your grip. Modern racquets are almost always made of such materials as Kevlar, boron and fiberglass, combining flexibility with strength.
