"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."

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 at 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.
