I think Ferrari should place some mix in the drivers seat. I'm not convinced that someone from F1 would be immediately competitive like Hulkeberg did in his winning stint in Le Mans with Porsche. Giving the fact that this Hypercar will have less downforce, drivers like Leclerc, Sainz would need a lot of practice to adapt well in these new Hypercars.
It could be like the old stories when F1 drivers passed to race in DTM and they struggled.
I've not read the names of Calado and Pier Guidi. Again underrated maybe, but both very fast and successfull in the GT programs of Ferrari. I would immediately slot them both in the Hypercar programme
