Fantastic string.
This is a really fantastic string. I'm switching to it from Hyper-G. I love the control and launch angle. Power and spin are good. Love the price and customer service!
Tip: Use Firewire in the crosses for more bite on slice/serves.
Mike 2
Top Poly on the market for one of the best values.
"I typically use Babolat Rpm, or Volkl cyclone and those were my favorite and Go to poly's and after Using tour status im making the switch The playability of the string lasted so much longer than Rpm and Cyclone. Im currently getting about 35 hours of play and that's in a Poly-Gut Blend, I can only assume that a full bed of this string will last even longer."
Isaiah
Power and Control.
"I was surprised and amazed by its power and control. I was able to hit the ball to so effortlessly. It was very arm friendly, as well. Its the best poly string I have ever used."

Official Product Reviews:
Excellent Hybrid Combination.
"T1 Firewire boost hybrid is an excellent overall string. In the past I’ve used Volkl Cyclone and different soft strings in the crosses. This combination that Tier One has put together is perfect. I get very good pop, control and spin. Arm feels great after playing. Also great tension maintenance which I feel the Volkl lacks in that department."
Eddie
Literal Game Changer.
"I have used a host of strings in the last year looking for something that plays like I like but also seem to be easy on my arm. I Have found my string. Firewire boost has literally changed my game. I can hit with great control, great power and spin and excellent touch. For me it really is the best of all worlds. I have it strung in a Prince Textreme Tour 95 at 50# I get great power out of it with this combo and my arm has never complained."
Steven
Absolutely love it.
"I used to use luxillon rough and nxt control and thought it was a great setup. I am usually a defensive 3.5/4.0 player. I won my first two matches ever at 4.0 singles playing this string and was able to be much more aggressive and kept the ball in the court much better. I could not be a bigger fan of this string."
Todd

Official Product Reviews:
The right string for me.
"At first it was difficult to wrap my head around the unique feeling of the string. It felt soft (I like to string my polys at around 52 lbs) but not lively. I was surprised how well I was able to control my aggressive groundstrokes and the amount of spin I was able to generate. I play the 16 gauge and as the string name Durafluxx already describes - exceptional durability for a big hitter like me."
Pete
Perfect for college.
"I play D1 college and my coach just bought a couple of reels of Durafluxx 16g from you. He told me to give you guys some feedback on this string. First, I have to say I never played a string that felt that way. It did not give me the usual crisp sound that I am used to playing with poly. It rather had a more muted sound to it. Although I was not used to the low powered feeling of the string the overall performance was exceptional. Great control and ball pocketing. It really allowed me to take full cuts on the ball without ever having the feeling of hitting the ball too deep. Durability was better of what I am used from other polys we usually play. I would definitely recommend this string to any player who breaks strings and likes to take big cuts on the ball!"
Sammy
Will get a reel
"YES, thanks Tier One for sending me a sample of Durafluxx 16 g. Awesome string. It performed exactly as described on the package. Great control and durability, nice recoil which I very much like in a poly. Stringing was easy and for $9 a set I will be a buyer."

New favorite String!
"I am very surprised about the quality of some of the lesser known string brands nowadays. Triumph is one of them. Amazing comfort and feel. Impact is as smooth as it can be which is a big plus for my arm. I am a 5.5 player and the string lasted me for about 12 hours, which is probably a couple of hours longer than I usually play with Wilson NXT Tour. Most importantly I will be able to save $6 per string set!!!"
Chris
Smooth and affordable.
"I recently had a few sets of Tier One strings set out, they were amazing. I used Triumph in a hybrid with one of their poly's and it played like Natural Gut, its a soft and really easy to control shots with. Loved it!"
Matt
Triumph performed better in comparison to NXT Tour almost on all levels.
"I tested Triumph side by side with Wilson NXT Tour because I was told that it plays similar to NXT. There is always a degree of doubt about the quality of a "no name" string.
Stringing was easy like any multifilament string. Hitting the first few balls, the string had a very smooth, soft response. I was able to control the depth of my strokes nicely. Drop shots and volleys felt great. Very good feel. But the string did not lack in power either. I was able to hit my spots at the serve and had a few aces. Although the string lacked somewhat in spin (especially in comparison to the new generation polys), I was able to generate enough for my kick serve and ground strokes. Durability: The string started to fray at around hour 5 and broke at hour 6.
I would highly recommend this string for anybody who like to play with an arm friendly multifilament string (like Biphase, Xcel, etc.) but does not want to pay $17 for it."
