Been hitting with Head for 30 years. Changed to Wilson N code 6.1 and received a free gift of severe tennis elbow. Went through my quiver of Head racquet's, different strings and tensions to relieve the problem and pain. Finally settled on Flex point Radical Tour MP 100, flex of 58. I finally strung it with natural gut 2 lbs under the middle. At Oz it works great for me and no arm pain. I only have one and I see one advertised here and someone posts where was it made, look on the butt cap. Mine says Czech, the one for sale says China. Could I tell a difference?
