chipping sounds easy and all, but if you're not used to doing it, it could get a bit ugly and embarassing. she could certainly work on it. it's a less flashy but very substantive play that works at all levels. with her wingspan
she should be getting to net MORe period.
mishit one chip though in a match, and you usually notice the player doesn't go back to trying it. something like that sticks with them more than pummeling a backhand return into te net. don't ask me why. it's all about comfort, and thats the best explanation i can give.
