Spin & Comfort
I am a 4.5 player and have a semi-western forehand with lots of spin. I strung it on a Wilson RF Autograph at 53 pounds. After the first hour of session time, the tension dropped by around 10%. After the second, it dropped by 20% and it stayed this way until the strings broke after around six hours of playing time. All tension measurements were done by the ERT 300 tennis computer and the string performed the durability on average for a polyester. The great difference was the amount of spin this string produces, that was almost impossible to hit a ball long no matter how strong I tried. This string is extremely soft on the arm and no movement was observed, until the last minute before the string broke. At this price too, it will be my string from now on.
