Superga as a pass before descending into Torino was something used only in the 90s/early 00s, before there were only some little hills close to the finish like the traditional Paris-Tours route and the older traditional route was totally flat. When Vegni decided to go back "to the origins" was clear that was a flat race or similar, the only thing you could realistically expect was more mileage and a surrogate for the Poggio if he wanted it to work as Sanremo tune in, but it's Vegni, so...
On a side note now we could have some faith regarding a better route for the Piemonte, something like 2020 would be good even if i fear an Oropa unipuerto, and also a better startlist with a "rest day" after Tre Valli.
