I'm using a Dunlop 200g HM. strung with 17g gut. Not synthetic gut. @ 55lbs. 55lbs is the low end of the range. This setup works well for me, very accruate, plenty of power and arm friendly. There's really nothing I dislike about it except I am not able to get a lot of spin on the ball. I understand with the dense string pattern of the 200g spin will be limited versus an open string pattern. So I guess the question is, will a different string impart better spin?
