Tecnifibre ATP Razor Code String Review 

www.tennis-ware...
Tecnifibre ATP Razor Code is a medium firm co-poly designed for big hitters who favor a crisp response. Our TW playtesters found this one to provide remarkable precision and very easy access to spin. Unlike traditional polyester strings, ATP Razor Code is built with special additives to improve comfort and increase power. The upshot is a slightly livelier and more responsive control string. In addition to being a great option for the advanced player, this one has enough all-around playability for the strong intermediate who wants to make the transition to a firmer control string.
