I like my Head Classic mid in almost every way, especially for its feel and great serving capabilities. But I just cannot hit a very good penetrating slice backhand with it. It's nearly 1.6 years since I play with this racquet but I'm still not able to get the ball penetrating deep enough in the court with good slice. When I do hit it good, it still doesn't have enough power, but when I try to get a little more swing behind the sliceshot, it ofton floates meters passed the baseline! I also have a POG, I don't like this racquet at all, but I recently found out, how easy it was to hit a very good sliced backhand with this racquet. Would the dense string pattern be the problem, or my technique?
