I playtested Dignics09c once. it wasn't on my blade, unfortunately, but when I saw the sponge hardness I just couldn't believe it, it plays much softer. i.e., I played quite a lot with Xiom Omega VII China Guang and sponge hardness is similar but O7CG plays much much harder. Donic BlueGrip C2 plays similarly, but didn't gave that much catapult and also, you know you are playing with 55 sponge ... didn't play with Gewo (yet) but hopefully you did with one of the other two I mentioned and you can compare ...
