POLYTOUR Fire 120
Players with long, fast strokes should love Yonex Poly Tour Fire - a round polyester monofilament that will keep your biggest strokes inside the lines. The feel is firm but nicely dampened, with a surprisingly low level of shock on off-center hits. Yonex has made this string with its unique Silicone Oil Infused Filament (SIF) Technology. This is a manufacturing process that reduces string bed friction, enabling the strings to snap back with vicious force (resulting in heavy spin). Our TW play testers were impressed by how much control this string offered on full swings.
