With all the ideas about how spice up the show, the idea from Pirelli to allow the teams to pick different compounds has easily worked the best. Prime example as mentioned is Haas who drove an aggressive strategy on super soft and made the others look silly.
Mediums didn't work for William's at all and I'm confused that they ran on them for as long as they did, Bottas changed to softs at the end but the damage had already been done.
As for the turn one incident, it was as 50/50 in my view as well. Lewis left the door dangerously open into turn one. Bottas did not lock up or slide into him. Whether Lewis even saw him coming in his mirrors I don't know (assuming he used them!
