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.”
