TecnifibreNRG2 17g (1.24) Black Tennis String - 40 foot pack

I'm a B-level player in my local club (NOT B level open/pro). Power is increasing but I am not a string breaker. I play 3-4 hours a week and replace strings every 8 weeks or so. I've kept the NRGs for a little over 3 months and the fraying is there but not close to breaking. I'm only replacing them now because I've lost some accuracy on my kill shots and that's an indicator for me the get some fresh strings. I've tried many strings and have found these to outperform others in terms of power and durability. Ashaway Ultrakills are a close second but playability was not as long. I'd rate the NRG2 as follows: NRG2>Ultrakill>Pro Kennex Liquid. Loved all of these strings and they have a better feel than Head Megablast (replaced after 2 hours of play...did not like), Python (felt dead to me) and the like. Any of them, especially the NRG2s, are worth the premium pricing if cost is not a factor to you.

Absolutely love this string! Not a professional tennis player but do make it on the courts 4-5x a week when weather permits. For reference; 3.0 player so I’m not hitting 90+mph serves. Purchased due to having tennis elbow and wanting a little more spin and power. Noticed a big difference upon first use! Hit the ball moderately hard for a woman and no issues yet with fraying or breakage so I’m happy! 🎾 🎾 🎾🎾🎾

Best Non-gut string on the market for feel, playability, power. It's good for spin however if you rely on your string for your spin, which you shouldn't, go with one of the grooved strings and forget about the great feel, playability and power of this string. This string is the closest to gut that I've ever used. This feels more like gut than even the Wilson NXT which is known for that attribute. Durability of this 17G is not good. You'll need to restring about every 4-6 weeks. If this is to often, then go with the 16G of this string. You'll get a couple months out of it.

Bought this to use with a Head microgel radical MP 98inch, had it strung at 54lbs (the racket minimum is 52lbs, so I considered a little of tension loss)Very comfortable, also I was surprised how good it sounded, a rather strange thing to appreciate but it got my attention in a good way.The pop is reasonable, I wouldn't say the best, but it compensates with excellent ball pocketing.

I really love this string, but it doesn't last that long for me. Some may have better luck, but I'm getting about 3 matches which is typically two sets. But that's average for most multifilament strings at 17 gauge - at least for me. I have four racquets and I also do my own stringing so it's not a big deal although a bit pricey over time. The strings do feel great.
