A trend in tennis right now is to string rackets at lower tensions. On some rackets, such as the Wilson Clash, stringing at 45-50lbs is recommended.
Should you be stringing that low?
That depends mostly on the racket you are using.
Just because someone you play with is playing great with a racket strung at 45lbs, doesn't mean that it will work on your racket. All rackets have a recommended tension range. Depending on your racket, 60lbs could be at the high end of the range or the low end and will play very differently.
Another thing to consider is the strings being used. Some poly strings such as Luxilon, suggest stringing 10% less than with other, softer strings. Like with rackets, 60lbs with a poly string will feel much different than with a multifilament.
The main thing to know is what are you using now, both racket and string-wise, and what sort of results are you looking for. We can help you find the string/tension that will be fit your needs and your racket.
