well i finally broke the strings on my nsix-one. im still undecided about where to string my racquet at. the best choice would be my tennis coach because i see him every day for school. would PSGD 16 be good on my nsix-one? im pretty sure he has reels and reels of it. and it would cost me $15 including strings. compared to $20+ for stores(sports authority, academy) WHAT SHOULD I DO?
