Mercedes have been quick in qualifying all season, and Canada and Monaco are not tracks that would show up Mercedes shortcomings quite as much (hence Hamilton getting two top 4s and Rosberg winning in Monaco) as teabagyokel has said, tomorrow is the proof of the pudding as the nature of the track isn't too dissimilar to Barcelona, where Mercedes took pole, but fell backwards very quickly in the race, my moneys still on Mercedes being behind Red Bull on race pace, but it wouldn't surprise me to see a Mercedes driver on the podium
