Tier One Sports Black Knight - Co-Poly Tennis Features

• What makes this 6 sided co-poly string so truly special is that although, it is very soft/arm-friendliness (based on USRSA lab results), it holds tension extremely well (based on USRSA lab results), offers outstanding durability AND provides the high level player with precise depth and directional control. It is common thought to assume that the string would respond very "springy" and loses tension quickly due to its softness. Quite to the contrary, this is one of the string's strengths!
