Tier One Sports TRU PRO Black Knight - Tennis String (Poly): for The Tournament Player

Incredible string!I used to play in college and I love this string. It gives me enough power to put the ball away. High durability and tension stability is amazing. It has been about 7-8 hours and I don’t see any performance loss yet! Great string!

After testing numerous strings, it always brings me back to Black Knight. At 50lbs. this string feels perfectly balanced in power and control. Great access to spin and an arm-friendly response makes this my go-to string.

I have used this as a main string in a few racquets, different gauges depending on the string pattern. Thicker gauge for 16x19 and thinner gauge for 18x20. In both variations I used their Ghost Wire as the crosses in the same thickness. This combo has worked very well in each racquet I put it in and I will continue to purchase it as it is a good buy for the dollar amount.

After playing with hyper g for almost a year, I tried a set of Black Knight and fell in love with it. Great performance on all levels!

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.

It is durable and good for the price.

Haven’t been able to use the strings for an extended amount of time, but they’re decent, quality strings. Wouldn’t put them on the same level as Luxilon - which, I think, is their goal. Are they the generic cola to Coca-Cola or a less expensive, but comparable, version of a high quality string like Luxilon? I’ll come back after I’ve had more time with them - but, so far, more in line with the Coke analogy.

The 18 gauge provides a nice feel from the baseline and at the net as well as solid power (I go with 52-55# tension with a Yonex VCORE 100). You can't beat the Tier One Customer Service! They are "Aces" ;-)
