BLACK KNIGHT Tennis String Set (40 feet/12.2 m)

I find this string to be high in power, spin and consistency. It plays on the softer side which makes it unique. Crossed with Ghost Wire, this setup softens the response while maintaining control, power and spin. I'm not the biggest hitter, but I take a full swing on every swing.

I have been using this string for a long time. The only issue I’m having is holding its tension. But I really don’t see a drop in tension until I’ve played for at least a couple of weeks. It holds tension for plenty of time, but the string does loosen after a while which just means it’s time to string it anyways. Great string all around. Super soft on my arm and wrist.

Had this strung in my CX 200 which has a slightly tighter sweet spot and the string played very predictable. The best part was the playability over 3 weeks was great and predictable contact stayed throughout. I played a doubles match on the 3rd week and it still played the same although slight tension loss. I used the 1.23 and it was very comfortable. Next thing is to try it in a open string bed to see if it plays the same.

I got this along with a package of Firewire for a Yonex vcore L. I had intended to use the firewire, but after trying both, I found I played better with the black knight. It's more comfortable, and I expected that, but I also found I had better control with it, which I did not expect. I'm sticking with the black knight.

After trying about 20 different strings the last two years ( I never seem to be satisfied with a string) I finally found Black Knight that gave me the security in mine strokes that I was missing in all the other strings. Many thanks for this string and now I can concentrate on mine technical skills!

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 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.

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 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!

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.

It is durable and good for the price.

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 have been playing with Black Night for a bit of time now, around 4 months. Really enjoyed it from the first string job with its very balanced approach. It simply manages to take attributes of comfort, control, power, spin, pocketing and predictability into a beautiful balance. Very nice job Tier One!

I really liked firewire and boost when I purchased the first timer bundle, and felt kind of bummed out that T1 didn't sell the Neos-2 as a standalone set/reel. Decided to give Black Knight a try as a cross to natural gut in the hopes that it would be slippery enough and not too sharp despite the 6 sided profile that it would not shred the gut mains. I'm a 4.0 player and don't now how I would play with Black Knight as a full bed, but as a cross with natural gut it does a fantastic job of taming the power of the gut mains and bringing its control and spin characteristics to the stringbed. Currently 12 hours in and playing just as well when it first came off the stringer with amazing tension maintenance. Only caveat to this review is that my racquet is 18x20 so it helps on the string longevity factor. Black Knight is also softer than the other poly strings that are known for their tension maintenance, so the gut/BK combo is definitely a winner for me.

I was a 4.0 player satisfied with T1's Boost. When I ordered a reel, out of curiosity, I added a pack of Black Knight. I expected to hit with it a few times before cutting it out and returning to strings appropriate for my middling level. I did not expect to order a reel. With other strings, I am aware of pocketing, pop, spin, etc, but Black Knight just disappears and the ball goes as directed. The only description I have is, perfectly balanced. Sounds vague but nails it. So my only complaint is marketing it to 5.0 and above players, but maybe I am wrong. Maybe it has turned me into a 5+ player.

This is a great string! I used the 18 gauge in my speed pro 18/20. It's shaped design provided great amounts of spin. Pretty good control and just a tad more lively than other polys, but that may be because of its thin gauge. No arm pain, comfort is slightly above average for copoly. Tension maintenance was decent; it may have not impressed me in that area because of its very thin gauge. Should have ordered the 17 gauge. But I would say tension maintenance is close to as good as hyper g, certainly better than cyclone. Tremendous durability, it would take about a week and a half to break these, even in 18 gauge!!! To put it into perspective, I broke diadem elite xt and luxilon Alu power spin recently in 4 days. This string is like a crisper solinco Revolution, much better than volkl cyclone. I am a pretty hard hitting, Texas super champ, highschool player.

I am tennis coach upstate New York and have now become a repeat customer for this new poly. Based on my string expertise I would recommend this string to high level junior and adult players, in particular for players who can generate their own ball speed. Tier One Sports - thanks for the initial sample.

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!

Good string, performs well with my aggressive groundstrokes. Will consider buying a reel!

I used to play Tier One Durafuxx for a while and was very satisfied. A friend of my introduced me to Black Knight and WOW. I am playing adult tournaments and consider myself a 5.5. Will be sticking with this string for a while!

Tier One markets this string for high level players and they are right. For me as a Division 1 players this is the ultimate string! Excellent in every department.
