Yes I think with the long pit time, hard overtaking, low fuel consumption, and medium tyre wear, the best strategy is going to be a one stopper. I am not sure what tyres to use though, probably hard tyres, but there might be a chance of medium tyres lasting.
If you do Q1 on a tyre, you are then committed to that tyre for the race, right?
