I need to pick a poly cross string to go with Pacific Tough Gut 17 mains on a Dunlop Biomimetic 100. The choices are: Pacific Poly Force 17ga, Isospeed Black Fire 17ga, or Babolat Revenge 16ga. What would you pick and why? The Bio 100's are leaded up and leather grip. I play a big serve and attack game with western fh grip and western backhand grip. Hopefully that helps. Thank you TT'ers!!
