Hey everyone, With all the hype about the new co-poly's, I am going to give them a shot. I regularly use Wilson NXT 16 and have no problems with it on my Dunlop Aerogel 500 Tour's. I have only used one poly before, Cyber Blue, and it went dead in 2 weeks. After that, I said I wouldn't try anymore. I have received several responses from the TW staff about two soft copoly's that offer great spin and tension maintenance - Signum Tornado and Gamma Zo Twist. One TW staff member said that he has been playing with the Zo Twist for several months and it still plays great. He said that the only reason it went dead once in 2 weeks is because he left it sitting in his hot car. If you don't do that, he said that I could atleast get a couple months out of the string before it goes dead. Is this true? I won't get to try them out till next year when it warms up since I don't play indoors. I only play 3 times a week. I don't want to hear anyone complaining about intermediate players shouldn't be playing with poly's. I just want to know if the strings will actually last this long before going dead. I will be using these in full jobs. Also, which do you think is better of the two? I will be doing a side-by-side comparison of NXT and of these.
