Razor Soft in short
Developed for Daniil Medvedev, who wanted more power and pocketing than Razor Code. Constructed with the same high-modulus polyester but with a unique polyurethane additive melted into the core. Despite the name "Razor SOFT," this is not a soft string - it offers more pocketing than Razor Code while maintaining excellent control. A firm but not harsh string with excellent control on full swings. Outstanding playability duration - a well-known weakness of co-poly monofilaments. Medvedev has had his best seasons since switching to Razor Soft.
Poly Tour Pro in short
Yonex Poly Tour Pro is a softer playing poly stretched at high temperature during production to improve tension maintenance. "I felt like I could put the ball on a dime with it!" - exceptional control on fast swings. The ball seems to sink into it like a pillow at contact. Despite being firm, it has above average comfort for a poly with the yellow version playing slightly softer than black. Not the most spin-friendly in the Yonex family (actually the least), but the control and predictable response make it a favorite among power players. Don't try to get more than a month out of it - when it dies, it's done.
