Nora Schneid Questions

1: What revenge tune is better for her?
2: I'm going boostrun on her, so would Tough Runner be of any use? I heard that it basically doubles TGH, in which case it wouldn't be very helpful. Can anyone confirm it?
3: If 2x clearance, fast recovery still useful?

Thanks in advance~

1: CV.
2: Tough Runner is still good no matter what
3: Depends on if you want RNG or not. I would do 2x CV with Fast Recov myself because fast recovery is permanent, and the CV is only "nice" to have.
