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.
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.”
For years the monofilament string market has been dominated by polyester — a substance that can be too firm and underpowered for less advanced players. About a decade ago, Ashaway’s Steve Crandall began working on a new concept: a monofilament control string with genuine comfort and power, closer on the stiffness spectrum to natural gut. In the early part of 2012, after years of testing and tweaking, Crandall finally found what he was looking for. It’s called MonoGut ZX. The ZX stands for Zyex, which is a much softer and more responsive material than polyester. On his most recent visit to Tennis Warehouse, we had the chance to interview Steve about his impressive new string. Here is what he said. Continue reading →
