What is the range or scale (from what to what?) on racquet stiffness? I am having tennis/golfer's elbow issues and have been told that a less stiff racquet is one element of help to look into. Right now, i use K Six-One 95. It rates a 69 on stiffness scale. I've been told that is really stiff. But I do not know where it falls on the scale. I have demoed the Babolat Pure Storm, with a stiffness rating of 64. To me it seemed like it had a lot of give to it (meaning less stiffness). Since 64 and 69 are numerically close, I need more information on the scale itself. So, my question, where does the scale begin, where does it end? Secondly, what stiffness number should I look for in a racquet to help address my tennis elbow problems?
