Tamburini, because he changed the course of my life. I would never have bought my first 900 if I hadn't been dreaming of a 916, and if I hadn't bought the 900 then I'd have missed out on a lifetime of dreaming in red.
That doesn't make him the best designer for Ducati, and I think the Supermono is still the most beautiful piece of automotive design ever penned, but it was a 916 for me, all the way.
Unreasonable emotion comes with owning a Ducati.
Cheers,
Ali
