How does it play?

This firm and durable co-poly is ideal for intermediate and advanced level players who like to swing big. Make no mistake though, this is not a dead poly made only for the biggest hitters. Indeed, what distinguishes this very playable control string is the high level of comfort and power. For this reason Firestorm fits perfectly inside the growing ranks of friendlier, more elastic co-polys like Dunlop Black Widow and Tourna Big Hitter Black 7. While this string is not likely to have enough pop or comfort for the player who prefers the ultra-soft feel of a multifilament or natural gut, it does provide big hitters with a cozy new option for adding some spark and spin to their game.

What our playtesters said

“You can really feel the ball jumping off the stringbed. I actually found I had to increase my tension a couple of pounds to harness a bit of the power and get the control that I needed.” 

“The ball sinks into the strings nicely, so when you do take a big rip at it, you are rewarded with good spin.”

“I found this string to be very comfortable for a co-poly. It felt like it was pocketing the ball exceptionally well.” 

“This turned out to be one of the longer playing co-polys I’ve tested. The longevity may be slightly to do with the higher reference tension I used, but comfort was never an issue for me over a four week test — very impressive for a poly.”

Strings for big hitters on a budget…

 

Don’t get me wrong, I appreciate the magic of Babolat RPM Blast …

….with its innovative cross-linked silicone coating, vicious snap back and otherworldly spin. I also appreciate the miracle that is Luxilon, especially on the professional tour, where strings like Alu Power have enabled the tornadic angular whip of the modern topspin game, allowing for exponentially higher levels of spin and control. Indeed, it only takes a few topspin forehands with either of these strings to realize why consumers shell out top dollar.

Does this mean you have to spend over $10 to get a good string?

If a polyester string costs less than $10 will it not snapback? Will it prevent me from reaching my personal best tennis? I humbly submit that the answer is “no”. Savvy consumers who are willing to poke around can find great performance for a low price.

For the love of Gosen

Of course, if you don’t feel like poking around, just go to the Gosen string page. There you will find the sorts of low cost/high performance strings that make home stringers giddy. More specifically, you will find the original Polylon, which prompted our resident polyester expert, Chris Edwards, to declare, “This string is legit. Sweet as a nut right off the stringer.” Needless to say, after a few sessions with Polylon, it’s easy to conclude that the $2.95 price tag is a typo.

For a softer feeling poly at a great price, there is the technology advanced Polybreak which provides the incredible spin and control of the original Polylon but with a slightly more flexible response. Finally, no mention of Gosen is complete without paying homage to OG Micro, an extremely responsive synthetic gut which has long been the standard-issue reel for stringers in need of reliable hybrid parts.

And Tourna . . .

Poly players who have not experienced any of Tourna’s co-polys are hereby advised to make some room on their demo list for Big Hitter Silver and Big Hitter Blue (which both come in Rough versions for added grip). These innovative co-polys are not only loaded with control, spin and feel, they are steals at under $8. For players who like comfy (yet crisp) polys, Tourna Big Hitter Black 7 offers a combination of bite, comfort and control that is near impossible to beat for under $10. As someone who ran lab tests on the early prototypes of this string, I can safely say that the Tourna crew is extremely serious about meeting their design goals. They also have an ultra-comfortable multifilament called Quasi-Gut which is softer than NXT and NRG2 (at half the cost).

MSV and Topspin

Big hitters on a budget do not have to sacrifice liveliness or comfort as long as Topspin keeps making Cyber Blue and Cyber Flash. The results from our TWU lab tests place these amongst the softest polys on the market. Another company with some impressively playable low cost polys is MSV. You can start by reading our string review of Focus Hex, a medium-firm co-poly with incredible control. After that, give both Co-Focus and Hepta-Twist a serious look. These meticulously engineered co-polys fit perfectly inside the growing ranks of elastic, user-friendly monofilaments, offering advanced players a friendlier response without sacrificing any spin or control.

Gamma Zo Magic 16 String Review

The Gamma Zo Magic 16 gauge string is advertised to be a very soft co-poly with very good tension maintenance. Sounds like a good combination to me…and so I gave it a try!

I strung up the Gamma Zo Magic 16 in a Prince TT Warrior MP at my standard 56 lbs for a polyester string. The string was very soft and stretchy for a polyester, and thus it was a little easier to string than most polys.

My first impression of the string was that it was extremely soft, almost “gummy” feeling. Since it was so soft it was very arm-friendly for a polyester, and thus very comfortable to play with. It also provided me with a lot of touch and feel on my shots, which is not always typical of a polyester.

With that said, the Zo Magic did not feel great hitting off the ground. Since the string was so soft and gummy, it did not pocket the ball well and did not have very much “pop” or spin potential. I felt that my groundstrokes floated off the racket a little too much and did not have the heaviness that my shots would normally have.

On serves and volleys, the softness and feel of the string gave me lots of control, especially on touch volleys. However, I was not able to generate very much spin or power on my volleys and serves. This was the general dislike I had for the string.

The string’s tension maintenance was excellent. I played with it for a few days, and then went on a two week long trip. Upon return, the tension had dropped slightly but was very similar to its original tension, which is pretty impressive for a polyester.

With that said though, I did not particularly enjoy playing with the Gamma Zo Magic. It was very arm-friendly, but did not provide me with enough power or spin for my liking. If you have the desire to play with one of the Gamma polyesters, I would suggest instead trying the Zo Power, which is soft and has a little more pop than the Zo Magic.
