If I thought Pirelli were going to make tires that the drivers could push on the whole time - I would be for a mandatory single stop. The problem with the way things are now isn't that there are two tire compounds, it's that the two are crummy/crummier, instead of great/faster for 2 laps. At least one compound should work for the whole race, full stop - not just "last", but *work*.
Changing the frictional grip/down force ratio is how they should achieve passing, not "who has nursed their rubbish tires better". "Passing" isn't the flip flopping between opposing strategies at the end of the race, either.
