If you use pronation and wrist snap forcefully, you will produce rolling the wrist effect automatically, but most of it must happen after impact.
This is example of Hantuchova extreme wrist ulnar deviation and pronation actions.
This is very difficult shot because the timing becomes the main issue, but you can get both, very high ball’s speed and ball’s spin!!!
