This race again wasn't representative because of the one stop. Bahrain will finally give us a representative session about how the pecking order stacks up. The Mercedes isn't working that well in cooler conditions which is very positive sign because it means that it isn't picky about temperatures vs the W15 and also they're bringing upgrades to address the low speed corners, brakes, and tyre warmup issues which is extremely crucial to a circuit like Bahrain. So I sense their upgrades will be mainly on the suspension (front/rear) and inner brake drum redesign.
