This installment’s rubber: Loki Stinger China 57.5 degrees, forehand

Scoring scale: My standard: 6 is passing, 7 is good, 8 is excellent, 9 is very good.

Test setup: Stinger Flame Dragon (outer ALC), Stinger China 57.5 degrees, tacky on the forehand

Quick Take

Stinger China is a newly released rubber under the Loki brand, positioned for both forehand and backhand, in three hardness specs: semi-tacky (52.5/55/57.5 degrees). In the early hours of September 8, I tested the 57.5-degree forehand version.
The Stinger China 57.5 degrees uses a black cake sponge, 2.1mm thick, with a bare weight of about 70g, which is fairly reasonable.
The surface is slightly tacky. Pressing on the sponge to gauge hardness, it’s roughly equivalent to a 40-degree Hurricane.

Playing Impressions

Forehand drives: The feel isn’t very clear, and it’s a bit blurry under light power. The sponge hardness is high.
Forehand flat hits: There’s a certain power threshold to clear. Once you penetrate the sponge, it’s fairly crisp and bright.
On forehand contact, compared to other rubbers, you need to push forward a bit more, or add a bit more direct contact.
Forehand loops: After increasing the proportion of direct contact, both arc and power come through, crisp and powerful, with good speed.
On the sponge: After driving into it on a loop, you can feel the sponge’s support. At least backing off to mid-table it doesn’t feel hollow, since it has a 40-degree hardness base to work with. But once you back off to mid-table, the sponge’s upper-end power doesn’t keep scaling up. That said, amateurs usually max out at mid-table anyway, and Stinger China’s power is already plenty. If you need more power, you can pair it with a stiffer blade, or go with a 40-to-41-degree Hurricane.

From points 1 through 4, you can see that the tacky version of Stinger China 57.5 degrees, because of its harder sponge, performs only so-so on topspin balls under light power, with a clear performance jump once you power through and penetrate the sponge. But the transition through the middle power range isn’t smooth enough.

Stinger China’s serving game is fairly strong: it grips well, and although the spin is a notch below Hurricane, the ball-gripping and friction are still quite comfortable. You can rely on the topsheet to produce good-quality serves, and rely on the sponge to produce very fast long backspin serves and fast no-spin serves. Its long serves are more threatening than Hurricane’s, so I think it’s better suited to amateurs.
Stinger China 57.5 degrees doesn’t perform too well on flicks, because under light-to-medium power, when you can’t penetrate the rubber, the feel is uncomfortable. But flicks are a short, abrupt motion, and for amateurs, actually applying them in a match and penetrating the rubber is far harder than with DNA Dragon Grip.
Forehand push control: I’d give it an average rating. Although the tackiness is controllable, the sponge is fairly hard, so the feedback isn’t pronounced.
Forehand loop-drives against backspin: Similar to what I described earlier. Under light power, the arc on a brushed loop is very stable and easy to land. Under medium power without penetrating, the transition feels unsmooth, the sponge is hard, and it’s easy to miss. But once you power through and penetrate it, speed, quality, and landing rate all jump up at once, crisp and fast.
Final verdict: Stinger China 57.5 degrees is suited for forehand use by amateur players rated 1500 and above. Performance in every area is passing or better, but the light-to-medium power feel and transition are on the weaker side, requiring more forward lean and more direct contact. So I’d personally suggest dropping the hardness and going with the 55-degree version, which should feel better and could serve as yet another no-boost Hurricane alternative.

In summary, tacky Stinger China 57.5 degrees scores below 7, and tacky Stinger China 55 degrees gets a 7.
