I string my racquet a TT Scream using Prince Poly both mains and longs. Is this advisable? I have been on this board for a few years and never been particular on strings, just was using Prince synthetic strings before on both mains and longs. What do you look for in stringing the mains and stringing the longs? What type of strings? I notice a lot of people like to use different strings for the main and a different type of string on the longs. How do you go about choosing and what criteria do you use to pick strings?
