This track layout will definitely favour the likes of Merc and McLaren. Nice long high speed straights and very few sharp corners where RB normally have an advantage. Will be an interesting race for sure.
I think it was the FP2 commentators who mentioned all the teams and drivers have a plan until you get to turn 1 and see what everyone else does. There's a very real chance we have a melee into T1 and the race becomes a war of attrition. Time will tell.
