It’s not every day that a string comes along with the comfort of Tecnifibre NRG2, Babolat Xcel and Wilson NXT. Optimus, a new multifilament from Wilson, is just such a string. Constructed with an army of shock absorbing filaments, we think it will lighten the load on your tendons as well as any multi on the market.
But that’s not the whole story. Unlike some multifilaments that are mushy and come with an unruly “trampoline effect”, we found that Optimus, when tensioned correctly, had a wonderful crispness along with above average control for the breed. This somewhat unique response is partly due to a thermoset co-polymer membrane, which firms up the filaments in the core and slightly tempers this string’s elasticity. Granted, advanced big hitters and string breakers will likely not find enough durability and “snapback” with Optimus (in a full bed), but we think this unique multifilament is a strong option for the non-poly player who wants a great blend of comfort and controllable power.
The basic facts
Construction: Polyolefin Ribbons
Gauges: 17 (1.25mm)
Available in: Sets
Feel: Extremely Comfortable. Low vibration.
Recommended to: all ability levels, but especially those whose chief concern is comfort. A great option for players with tennis elbow. Also perfect for adding feel and vibration dampening to a hybrid.
How does it play?
Isospeed Professional Classic does not have the name recognition of Wilson NXT, Tecnifibre NRG2 or Gamma Professional. Nor does it have the higher price tag. What it does share with these iconic multifilaments is comfort – outstanding comfort. In fact, in the TW String Lab this string received a stiffness score that places it closer to natural gut than any of its more famous peers. The unique ribbons that make up Professional Classic are pre-stretched under high heat. As a result, this string maintains playability quite well while also offering a more muted and controlled response than comparable strings. Finally, no mention of Professional Classic is complete without noting its “Best of Class” vibration dampening. Aside from natural gut, there are few other strings that are as effective at adding comfort to a stiff frame. Anyone in the market for an arm-friendly multi or the perfect hybrid cross is encouraged to give this one a try. (And the price is awfully hard to beat)
What our playtester said;
“Soft without being mushy.”
“Installed at the top of the tension range, this string enabled me to swing big enough to generate good spin. Control was excellent and I didn’t give away an inch of comfort.”
“High marks for tension maintenance, and surprisingly good durability.”
“Touch around the net is spectacular. And it has a level of precision and predictability that is typically seen with much firmer strings.”
The basic facts
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.”
