I love hitting high slices, they bite pretty well. My low slices seem to work pretty well at keep my opponent back. However the slow medium height balls seem to always pop up and end up long. I know one possible reason is that I am hitting them too far around in front and this is causing my racquet face to open up. I really really hate slow loopers to my backhand sigh especially when I have to move more than a few steps and thus cannot setup for a backhand drive....any suggestions on how to handle a mid height slow loopy ball that you have to slice?
