A guy asked me to restring his rackets with Gosen HY-SHEEP (0.80mm) strings. What kind tension can this string take? Thank you. The rackets are all-graphite, and he's not clear with how much tension he needs. I'm thinking to put 20lbs to be safe.
The only thing I will worry about is the age of the string. Other wise, 25lb should not even be an issue. By the way, Gosen is still making HY Sheep.
I think the max tension for string before they snap is 40lbs. Depending on how old the string is the max tension will vary.
