"The ultimate poly for high-performance players"
What makes this 6 sided co-poly string so truly special is that although, it is very soft/arm-friendliness (see USRSA lab data below), it holds tension extremely well (see USRSA lab data below), 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!

Official Product Reviews
"35 year old open level tournament player. This string is a perfect fit for my game. Offers just the right amount of power and control. Excellent durability and it also keeps its tension until the string breaks. Will be ordering a reel."
Advance players string
"Fantastic string for the price with great bite. A very nice balance of control, power, and durability for advanced players. If you are not an advanced player look elsewhere."
"I always liked the quality of Tier One Sports strings but I think this is their best offering so far! I used to play national junior tournaments and now compete at high level adult tournaments. Control…check, durability….check, tension stability…check, playability….check!"
Small Business Does not mean lesser quality:
Our production team was able to develop a co-polyester compound that is superior in tension stability and string stiffness (softness) to most poly strings in the tennis industry (see lab test comparison below). We offer exceptional string quality often at lower prices than our competitors.
Qualitative Lab Test Results Do Matter:
There are 2 fundamental factors that build a foundation for the quality of a co-polyester string: tension stability and string stiffness. Having tested a great variety of strings from our competitors, we recognized the very limited number of strings on the market that perform well in both areas. Either the string is overly stiff or loses tension too quickly.
To offer some insight into the quality of our string we made sure to compare it to some of the "best", well known strings in the industry!
Tier One Sports: Black Knight
NOTE: Many co-polyester strings perform much more poorly in these two categories. Many of these strings are in a range of 230-250 in stiffness and 19-24 in tension stability.
