The main racket manufacturers are Wilson, Babolat, and Head. My preferences for rackets are either Wilson or Babolat. I prefer those rackets because they are durable and light, and they feel very good and well-made. I use a Wilson Hyper Hammer 5.3 because it weighs only 8.4 ounces and provides a crazy amount of power without me swinging very hard, so I can fine-tune my shots. It also is strung at a tight 60 pounds, so I get a lot of spin.
