## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Lots of spin, not too stiff!
  

*by P***E on Reviewed in the United States on April 2, 2017*

This is a very good co-poly string.  I have used RPM Blast (my previous favorite), Big Banger Alu, Cyclone, and a few others full-bed and in hybrid configurations: I like FireWire better than any of them.  This string has amazing spin potential! It also has a relatively "soft" feel (for a polyester)-I don't have any problems with it feeling too stiff or boardy.  I am using it at about 52lbs in a mid-plus racket and have tried it at 45lbs in a mid (93).

### ⭐⭐⭐⭐⭐ 







  
  
    Great control!
  

*by A***R on Reviewed in the United States on April 7, 2021*

I have found this string to give me the best control.  Not so much great power but I like control better than power.  I have this string in one racquet and another more power string in another.  While I go back and forth between the two, this string definitely gives me more control.  Will buy again.

### ⭐⭐⭐⭐⭐ 







  
  
    Awesome main string
  

*by A***. on Reviewed in the United States on July 23, 2020*

This string (red firewire 17g) is an amazing MAIN string. Spin, ball grab, feel, & playability duration are all top notch. (so-so on snap back). It pairs very well with kirschbaum PL2, or syn gut in the crosses. I did not like this as a full bed tho. 4.0 hard hitter (5.0s hit harder than me)
