New version not as arm friendly
I have been using this string for several years since I started having tennis elbow. Previously, the string had Fiber Fusion Technology and I loved it and my arm appreciated it. My recent order, the string package description changed to Performance Enhanced Technology and it was a little stiffer. After a few hours of hitting, my arm and shoulder got achy and I can feel my tennis elbow issue coming back. I am very sensitive to string stiffness so this new version does not work for me.
