Hi guys and tempted by the pro because of the gold hahaha i know it is very vain. Performance is better suited for me. Med stiff. I am not playing 6U (tantrum light infinity) at 26lbs and another at 24 lbs . I think this racket might be too light for me. or the tension cause bit of shoulder discomfort. My cross court slice having difficult imparting speed. So I am thinking of moving to Pro at 20 lbs or performance at 22lbs Like to know how does racket stiffness and tension relate to each other? So I thought stiff racket now and low tension and slowly move up the tension (Pro) Or Mid stiff with mid tension (Performance) FYI prefer balance head
