I know the sweetspot is at the center of the racquet. But can somebody sketch the sweetspot's exact location ? Cos I had some difficulty to pinpoint the sweetspot for my MP 88 @BG85-22lbs. ----------- | | | X | | | | | ----------- What is the radius of X ? If I string it at 20lbs, how much (%) more sweetspot will i get ? 5%, 10% ???
