Had TE in the past, from playing too much. 2 years ago I switched to the PK315 racquet and all is well with my elbow. Always strung with softer multis but recently a friend strung one of my PKs with polyfibre hexablade at 22kg and I really like the extra spin and control. I see that now there are many new generation polys that are softer. My elbow has been fine for 1.5 years and I want to start testing some of these new arm friendly co polys. Am I risking it, or are polys really getting more arm friendly? Is it better to go with poly mains and multi crosses? Would love to hear from those who are prone to TE but are using these newer co polys with no problems.
