How would you manage two title competing drivers?

We see a lot of discussion around how teams manage their drivers, how Toto has his favourites, McLaren have their papaya rules, Ferrari doing what they do…

Curious to hear what others think would work best to keep two title contenders happy? Should the first-second driver slots be filled in before the season starts, does it change each week depending on quali results? Do they just battle week in and week out?
