Well I'm no pro or anything but if you want a tip:
I was just looking at your draw, and you can't win when you bet on so many surprises. I mean, if Roddick and Granollers would play the final you would win 100%, but the chances of it are 0.00001%. IMO best thing is to put the likely scenario, maybe with one or two surprises. That's why many people put querrey a finalist - He is not ranked very high but big servers can always pull an upset.
Yup, that's good advice for this draw. I made the draw before most others and thought other people would choose some of my picks, but they didn't. Most of the time my draws are pretty safe. I just need to find a happy medium
