Is going gut mains/copoly crosses or full gut (or full multi) a good way of taming the stiffness, getting more feel and enlarging the APD's sweetspot? I know that in theory it will help but any comments are appreciated. I am worried that these setups will have to much power. Any strings suggested be it full bed or hybrid? NOTE- I used copoly full setup and poly main/ gut cross and is to stiff in this racket for me. The poly/ gut I can tolerate when hitting correctlybut the full copoly hutts my shoulder and feels to stiff.
