Seeing as everyone enjoyed the Monaco poll so much... 
All we know right now is that it is the softs (prime) and supersofts (option) and no one has any idea of degradation rates on these Pirellis at this circuit, this weekend. After seeing Bridgestone here last year though...
Track position must be less of an issue than we saw in Monaco which might push up the number of stops but can anyone imagine making as many as 5 stops work? Drivers only have 3 sets of options (and 3 sets of primes) for qualifying and the race. Stopping 4 times, means doing 2 stints on the primes and perhaps fewer total laps on the much faster option rubber...
Believe it or not, people wanted prizes for getting it right last time
So once again, those that get it right all get the "I told you so" award.
But that was not enough last time, so we had to have an "I told you so and I said it first" winner.
If you want to have a punt at the total number of stops too, then go for it. If you are stuck, then try this.
