What about it? - Hit with a leaded and small head size racquet (like the Wilson PS 6.0 85 sqi, if your normal racquet is a 95 sqi PSC, HPS or 6195) during practise to improve your swing and spotting on. I have found that hitting with a heavily leaded racquet improves my topspin groundies. When I go back to my normal racquet I kind of keep the loopy, down and up, swing that the heavy racquet makes me do, and my strokes are much improved, I think. However, I have not yet tried using another racquet - with smaller sweet spot. Any ideas? I am maybe planning on buying one.
