A friend of mine is trying to persuade me to buy Super String, a product from Austria in orange. He said that it is one of the best strings in the market and is not expensive. I couldn't find a lot online. I am hesitant to try it as I had tennis elbow about a year ago. I currently play with Luxilon Alu Power rough and Wilson sensation (Hybrid), but he insists that this is the best string ever. Anybody with experience using this super string? Any feedback? Thanks so much.
