I have been playing with VS gut in the mains and Lux in the crosses and I like the setup. I just broke my strings today at practice and my back up racquet has a full bed of Luxilon. I haven't used the racquet for a long while because I felt it was too stiff and it didn't seem to have the qualities that ppl claim to have. Now, when I used it today, I actually found the qualities that people were talking about. Now, my question is, if you string the Lux fairly tight, how hard to you have to swing to make it work. I currently use a APD that weighs 12.2 oz strung and I am do swing very hard. Is there a point where it doesn't matter how hard you hit it if it is strung too tight? I am going to ask my stringer to go full Lux but at a lower tension. I believed he told me that he strung by APD of gut and Lux at 64 a piece. Do you think going in the 50's would be better suited to get the most out of Lux. Thanks for any input!!
