Nice find! The spec on TW seems very different from the Dual Pro I used to play, especially the RDC68 stiffness. Not really sure if I can play it but 6pts HL is definitely a good enhancement over 4pts HL of the Pro One 16x19. It seems Donnay trying to add more power by increasing stiffness rather than keeping high swingweight.
