Max and Barry never met in Pre-FLASHPOINT continuity (unless you count their encounters as disembodied spirits inside the Speed Force, but they hardly interacted on those rare occasions), but if they were to meet corporeally, I think they would be great Speed Force debate partners rather than mentor and mentee. Barry's understanding of how superspeed works has always come from his scientific background and training; he thinks of speed in scientific terms. Max, on the other hand, has always treated superspeed from an intuitive, spiritual perspective. To have Barry and Max exchange ideas about their understanding of the Speed Force could lead to interesting results.
