Backhands against slower ball

Hi there with my backhand I can easily hit back a fastball and guide it back but say it was a slower maybe higher ball I'm not very good at attacking that. Any shot that would help me attack those slower balls.

Sorry if you don't know what I mean.

Thanks 

Hi Josh,

Take a look at this tutorial on how to Counter a Slow Spinny Topspin.  I think it will be what you are looking for.
