Ooh, get you! I went mid 1:13's, I think that seems as likely as any if its dry, (although I hope DRS doesn't massively reduce that). Wet is going to be a gamble, although saying that I have got Button for pole!
I've gone for a 1m13.130 on the assumption that it will be dry and the DRS will have a big effect. I gambled with a wet qualifying time in Malaysia and it didn't pay off. Not taking that risk again.
