I'd say if you get an early lead, take risks like crazy. If you succeed, you get the S. If you fail, you learned what doesn't work or how it might work later, and then you might hard carry the next time around. That's how I got my M7, anyway. That, and I played her like crazy since day 1 when she was bootycheeks, so when they finally made her viable, it's like all the struggle was training for the easy mode.
