Sectional Lvl player, avg size/weight. Presently plays with a 9.6 oz KSting. 2-handed both sides. Seems as the girls get bigger/faster she's having a tougher time putting balls away. Tonight she picked up my PK 7G and was crushing the ball (felt more like I was hitting w/a 4.5 buddy than my kid). Even served well with it. I doubt she could keep it up for a match, let alone a tournament. So what weight/SW would you recommend? At first glance I was thinking 10.7-11.0, 4-5 pts headlight (KBlade team or PB10 295). Thanks much!
