A gut main tension of 57 with a poly cross is 57*0.85 = 48.45 lbs. At the moment I have no real complaints about the string bed and these percentages are what I have always used in the yonex line.
I've read some where in this forum that poly string has the most trampoline effect at around 50-55 lbs. Do you have that same experience? Thanks!
