My blades will find your heart
But they wouldn't be able to block it because you do it during a combo...12, 22, f2 it doesn't exactly matter which you use since they're all 15 frames of Hit. I would recommend 12 or 22 over f2 since youll build more meter on block from the other two.
Or are you talking about followups after the BS4c?
