Racquet for 11 year old son..Help! My 11 year old son has been playing tennis for a year and he recently made our local middle school tennis team. He has asked for a new tennis racquet for his birthday. (The racquet he is using was very inexpensive and came from Wal-Mart.) I have been reading about power, control, head size, etc. I have no idea where to start. I would like to purchase a good racquet that will last through middle school. My price limit would be $150.00. Can someone please help me?
