I´m 42 years old and have recently(started in August) picked up tennis as my main sporting activity. I´ve never played for real before, but since August I try to play twice a week. If I were to judge my own level of play I would guess on ntrp 4.0. My style of play is to mostly stay along the baseline and hit mostly forehands with quite a lot of top-spin. My backhand is two-handed. In January I switched racket to a Babolat Pure Drive with Xcel strings. I really liked the comfort and feel of the xcel stings, but they broke after about eight hours of play. Instead I tried to have my racket restrung with RPM Blast at 57lbs. With this string I really liked the top-spin and control. They also seem to be durable. The problem is that if I play a bit more than usual, my elbow and shoulder feels a bit more soar than with the Xcel. So, the question is...is the a string with the comfort of Xcel and the durability and top-spin of RPM Blast?
