"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."

 Daniel

"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."

Amazon Customer

"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!"

Sebastian

"This is a soft co-poly suitable for a wide range of players. Good spin, control, tension maintenance, and comfort. Want a soft poly, look no further."

Amazon Customer

"I absolutely love the string. This purchase included my 2nd and 3rd package. I believe that I will be using this string full time. Shipping was excellent. I'm a very satisfied customer with Amazon and Tier One Sports. Thank you"

Michael Hensley

Marcelo

J. Halseth

"Great string! As a former D-I collegiate player and now having a highly ranked juniors son, we both are playing competitively with T1-Firewire. Definitely worth giving this string a shot. We did... and now it is the string in all of our rackets."

Tarmac

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.

"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

"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."

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

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

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

"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

"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

"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."

Ron

"As a 45 year male, intermediate player I was looking for a soft string with good ball bite and durability. This is exactly what this string provided me with. "

 Sepe

"Fantastic feel for a poly. An excellent choice if you want to switch from synthetic gut to poly, as advertised by Tier One."

Andrew

"I just can't believe this is a polyester string. The feel as well as durability and control blew me away! Thanks Tier One Sports for great customer service..."
