I think this works with Worlds where teams are still big and you have circuits and a very controllable race.
I doubt the useless breakaway gets any serious time.
Question is, with 5 guys a team, who will do the work from the start? Tratnik, Vansevenant, maybe Fraile or Juul-Jensen? Perhaps one of the INEOS guys because they're so used to pulling? But I doubt the Italians will make Moscon of Caruso pull, nor do I see the French using Cavagna or Cosnefroy.
I think it might be good for the bigger nations to get someone in the early breakaway.
