Comments: Great string. Very crisp feel but not tough on the arm. But it just pops and breaks easily, and thus the usable life is not too long compared to its cost. I have tried it a few times, and the cost vs. usable life is worse than gut (I am serious).

Comments:Should be around $4 to $5 because they do not last very long (about 8 to 10 hours, or 2 to 3 weeks max.). For an "all-around" string it plays decent (good feel, control, spin, power) but moves around a lot! I string it up 2 to 3 pounds higher, but doesn't help much (still moves). These strings do not shred like multis; they just pop/snap when they break because of the nylon copolymer single core string.

Comments: AWESOME STRING, good for control.
From: Jonathan, HB, CA, USA. 04/10

Comments: This string has very good feel but breaks in an instant! I also found myself moving the strings around after EVERY point. So if you are thinking about this string be prepared for it to break in a short time.
From: Jacob, Austinburg, OH, USA 06/09

Comments: Too easily to be broken. Has a good feel and hits very well, but only lasted me about 10 hrs. at max. So try it if you want to, but definitely not a keeper.
From: Frank, Ellicott city, Maryland, USA. 05/09

Comments: This string okay but it only last me a month. During the third week the string started moving and lose tension and I broke the string yesterday. I do recommend this string to anybody if you not a chronic string breaker.
From: Danny, Mountain View, CA, USA, 04/09

Comments: Good string but it BREAKS in a set. I use it in an Volkl DNX9, and it does not last even an hour.
From: Enrique, Lima, PERU. 6/08

Comments: Very mediocre string. Very little feel and precision. However, this string is pretty average in every category. Probably the best mid-line string on the market. I just recently tried the Gamma Professional string, and the feel and softness and precision are a huge jump. For just $10 more it's worth it. Also the Professional has better durability.

Comments: Pretty nice and soft string. Had it at 62# on Redondo Mid and enjoyed it for about 8 - 10 times out there (1.5 - 2 hours on the court). Then things started moving a lot and I started sending balls long. New strings are now on the racquet at 64 to see if it is going to help any. The first time out it felt a bit stiff and low powered but with excellent control! After a set either strings loosened up or I got used to them being stiff, but hitting was a joy! So, overall pretty nice and comfortable string with great feel, good spin and decent power (depending on how stiff you string it) well worth using it again!

Comments: I am a stringer and teacher in Sarasota, FL. I LOVE GAMMA! I have tried many different types of stings over the years playing and stringing. Gamma TNT 16 or 17 is great! I enjoy playing with both but I do prefer TNT 17. I love the feel and play ability you get with the string. No matter what string I try, I always enjoy going back to TNT 17. I play predominately on clay at 4.5. I am basically an all court player who enjoys coming to the net to end the point.
From: Bill Ciotti, Sarasota, Florida USA 06/06

Comments: This is a great string with a lot of spin, feel, control, and power. There's a lot of string movement and durability's not that great either.
From: Hugo B., La Crescenta, CA, USA 04/06

Comments: I currently use Gamma TNT 17 in the cross strings on my hybrid and the power is average, the control is good but there is no feel at all with this string. Overall disappointed at the string considering X-one Biphase costs a little more but is superb.

Comments: This is probably the best string I have ever hit with. It just has so much feel to it, but since I popped these strings so quickly (1 week) I can't say much about how it holds tension. Maybe if I do a hybrid with these in the mains it will last longer.
From: Alan Torres, Laredo, TX, USA. 04/05

Comments: GREAT STRING! I bought a reel of Forten Synthetic Gut 16 because it's so cheap, and I have been using it for about two months. Last weekend, I felt like indulging myself a bit of luxury and put on a set of TNT2 17. Much more feel and power! I thought stringing it at 60 lbs. would be unforgiving, especially in a midsize head, but there is no discomfort even for occasional off-center shots. Great string! I will compare it to Live Wire XP 17 next and see if the extra $4 is worth it, though I doubt Live Wire can top this!
From: Derek, San Francisco, CA, USA. 03/05

Comments: Great all-around string, I use this now almost exclusively. Good combination of power, spin, and control. Compared to Live Wire and NXT it has less power and pop, but more control and feel. It broke after about 7 hours of play. I'm a 5.0 player, all court and hit heavy spin.
From: Gary, Detroit, MI, USA. 10/03

Comments: This string is the best string I have ever played with. It has unbelievable power with great control. I am an advanced player who hits with a lot of power and spin. These strings have given me the perfect blend of power and control. I would highly recommend these strings to people who are looking for the ultimate string to improve their game. It has improved mine greatly.
From: Owen, Sheridan, WY, USA. 8/03

Comments: I've made a terrible mistake of trying Gamma TNT 17 after being pampered by Wilson NXT 17. Compared to Wilson NXT 17, TNT 17 pales in feel, comfort and control. The NXT allows the ball to stay in the string bed longer, TNT 17 on the other hand feels somewhat inferior.
From: Kelvin. USA. 5/03

Comments: I am a 5.5 baseliner newly using the older Head Ti Fire Tour Edition strung at 56lbs for the mains and 57lbs for the crosses. I am currently using TNT 17g as my cross strings and using Ashaway Kevlar 17g for the mains. For me it has been an awesome combination. I was previously using 17g strings but with Prince Synthetic Gut with Duraflex and I found that the Prince frayed more on more after a couple hours of heavy hitting. Once I switched to the TNT 17g, I haven't looked back. The durability as a cross string is perfect. I play 4-6 times a week with match play mixed in and the string job will last me about a month. I'm fine with this since I'd prefer to put a new string job in at about that point anyway. I did not like it as the solo string in my racquet as it lost tension and felt dead. Overall: Enthusiastically recommended!
From: Efren, Overland Park, KS. USA 1/03

Comments: I personally did not like this string. It had very good power and spin and the control was decent. I played with these strings for about 4-5 hours then I let my friend use it in a match and they broke. It is a decent string but the durability is horrible.
From: Robert, Taylor, MI. USA 4/02

Comments: Gamma TNT 17 gauge is the best string I've ever played with. To me, it compares to natural gut and is much cheaper than gut. The ball feel is incredible. It never felt this way with any other strings. The only drawback that I found was that it leaves an oil deposit from the strings on your stringing machine.
From: Sylvain, Paris, France 4/02

Comments: I've always played with synthetic gut and then I tried Gamma TNT 17 and the difference was night and day. The ball now feels better when it hits the racquet. I actually can feel the ball staying longer on the string - giving me more feel. Very good performance.
From: Joe, Virginia Beach, VA., USA 1/01

Comments: I've used Gamma TNT pro plus 16, and TNT 17 for my frame and found exceptional playability and feel. Being a 5.0 level all-court player, I love variety and am a string fanatic. Normally 62-66 lbs is my tension range. I like the control.
From: Gaylord, Boston, Ma. USA 9/00

Comments: Gamma TNT 17: great string, touch, spin, control, feel. Unfortunately, the price for all that seems to be durability; love the string but cannot afford the breakage. I do hit with a lot of spin but am only a 4.0 level player. Suggest 16 gauge for better longevity.
From: M.A, Hilton Head, SC. USA 7/00

Comments:Gamma TNT 17 is a great playing string. It combines excellent power with control. I recommend this string to anyone.
