Looking for some suggestions for string for an old friend of mine. He going on 60 now and he needs a more arm friendly string. He has been using big banger orignial since it came out. He loves the string and doesnt want to part with it but might have to as his shoulder has been giving some pain now. The guy is an absolute great player. Ive seen him beat up on college players and teaching pros. Hes also incredibly fast and mobile for his age. Im pretty sure what hes looking for is something with comparable control qualities but a little easier on the arm. Anyone have a suggestion?
