Yonex Poly Tour Pro $40
Poly Tour Pro 1.25 is a round shape yellow colored string. It’s softer feel provides greater comfort. It is used by professional tennis player Nick Kyrgios.
I can string this at low tensions and it is so easy on my arm but still offers plenty of spin and control. The best string I've used so far.
These string never break. They feel soft at 50 lbs and are great for volleys and spin.
IExcellent string overall and very impressive durability. I have been able to go for my shots without fear and even if it is round poly it surprisingly offered a great spin outcome.
