Anyone have a recommendation for a racket for a 9 year old girl (my niece)? She's 4'5" tall and weighs 61lbs. She's been taking group lessons for about 7 months. I've hit with her a few times (mostly handfeeding balls) and her stroke mechanics are not bad. She loves to hit. She'll be taking more group lessons this summer and I'll probably hit with her a couple of times a week. Her current racket is a 25" Wilson ATP, which is an older racket that looks to be all aluminum. One day she forgot her racket, so she used one of my daughter's old rackets, an adult size Prince CTS Lightning 110 (100% Graphite). She choked way up on it and said she liked it more than her regular junior racket. Is there a better junior sized racket that I could get her ? Some of the ones I saw at Sports Authority look more like toys than rackets to be used for tennis.
