I am going back to my favorite racquet. t320. I am a 4.0 baseliner 70%singles 30% doubles(prefer singles). I am getting back from a wrist injury and I unfortunately think I must depart from my beloved BHBR. Should I try gut at a hi tension or can you guys offer some ideas on a comfortable poly(prefer) or gut or hybrid(never tried) that will tame the power of this stick and that can be strung somewhat hi to accentuate the control that it has. thanks for any ideas.
