No problemo, this is one matchup I've played quite a few times
I wouldn't pick Grandmaster for this matchup tbh, the clone just gets nullified by knives. And if Sub thinks of hiding behind clone and doing an armoured move through knives to get in then ex knives not only goes through the clone, it also shreds the armour AND the third knife hits Sub lol. I think Unbreakable and Cryomancer are better choices, Unbreakable because it makes his zoning less effective (chip is still chip, any damage you can avoid taking is good) and therefore brings down Cybernetic's overall damage slightly and because you can mix up your close up game with the threat of parry and Cryomancer because of the higher damage output and 2 bar "vortex" I guess you can call it lol. I just think Grandmaster is tougher since every clone outside the corner becomes useless and he's not getting much started unless he manages to open Kano up and get him to the corner. Grandmaster's more complete in terms of tools in general but for this matchup I just don't see it being Sub's best choice.
