Spin Chal
A defensive rubber with a non-tacky compound, enabling heavy-spin chops while retaining bite on the counter-attack.
About this product
Spin of 11.5 with a speed of 8.5 — the lowest speed of any inverted rubber on this list.
It leans toward spin much as Hurricane 3 does (14.5 spin, 10.25 speed), but with less spin and less speed than that rubber. On the figures alone it looks like an awkward position.
The ₩39,000 price clarifies it. This is among the cheapest inverted rubbers here, and low speed means a low chance of the ball running off the end. While you are learning to brush the ball over, that is an advantage.
If you have reached the stage of needing power, a speed of 8.5 is a plain limitation. This is a rubber to learn on, not one to stay with.
What the numbers say
Inverted, 37.5° sponge. Its spin of 7.9 ranks 9 of 23 rubbers, on the high side. The other axes sit at a similar level, so the profile is well balanced. Based on the manufacturer’s published figures.

Where this rubber sits among Nittaku inverted rubbers
Speed and spin figures Nittaku publishes for 14 of its inverted rubbers. Nittaku does not state a maximum, so read this as relative position within the family. Further right is faster; higher means more spin. Other brands use different scales and are not mixed in.
