Well they both have the same cover ,......but totally different cores and dynamics......the AI is symetric and the S&A is a strong asymetric.
By nature......all things being the same (which is VERY difficult to do w/ these 2 balls, but suppose you could...) the AI will be smoother overall, while the S&A will be bigger on the backend....both covering a similar amount of boards.......
