Inception

Spin and speed are both exactly 10.5. Only this and Donacle Long-1 share identical figures on the two axes here.

Hardness is on the firm side at 42.5 while the figures sit mid-range. A hard sponge with modest numbers usually describes a rubber that needs to be worked hard for a return that is not especially high — which narrows who it suits.

The key to reading it is the ₩39,000 price. It is an inexpensive way to find out how a firm sponge feels, and having established whether 42.5 works for you, the route upward is Genection at the same 42.5 for ₩138,000.
