Hi, my current strings setup is: Isospeed 17 Classic at 52 pounds. I play with a semi western forehand (moderate spin) and one hand backhand (eastern grip), mainly doubles. With the current setup I am lacking in the control department and I would like a bit more of spin from the string bed. I can't play with poly/co-poly string. Could you please recommend strings (synthetic gut or multi) that they play well with this racket? Thank you.
