What tension should I have my racket strung at?
You should always stay within the manufacturers recommended tension, this is usually displayed on the inside of the racket throat. That said the higher the string tension will result in the ability to hit more spin but will be less forgiving on the arm and the lower the tension will result in more power with a bigger sweetspot. There is usually a little trial and error before you will find the perfect tension for your playing style.
