I am a 60-year-old 4.5 tournament player and have been looking for something more forgiving to replace my Babolat Pure Drive. This racquet is it! I tried the Babolat AeroPro, Prince 03 White with/without ports, Prince Speedport Black. All had unpredictable power and little feel on touch shots. This 03 Hybrid Comp has an 950 power rating, a little less juice than the previously mentioned racquets, thus more control, and its flex gave it a nice soft feel. Have leaded it up by 1/2 oz. and it still feels great. Demo it before buying any hacker's racquet.�€� - Jose, Bradenton, FL
