I ask as ive justed snapped my gut string, sliced through by the alu rough in the crosses in a matter of minutes. On playtest with this set up my serve was just amazing, side swerve, kick, spin, pace etc etc I usually get loads of spin with my full poly set up but not this kind of power. I am still getting plenty of spin with the gut/alu set up but my question is, is the alu rough in the crosses having a real affect on my spin etc other than stiffening up the string bed and helping with control? Do the crosses really help with spin (i know it must do to some extent) but couldnt i get away with a tighter all gut set up so that my poly doesnt slice thro it? Or should I go back to my old set up (but other way around) with x1 in the mains and PHT in the crosses (doesnt rip thro as much as alu rough)?
