1st question: We will only know when the season starts! The test... well, last season Vale's Yam seemed to be ok, but then, you all know what happened!
2nd question: I think that Lorenzo will do all he can to win but he still has to get used to the bike. We'll see great races and positions fight, but I'm not sure if he will "protect" Vale if he needs! And we can't forget that they're using different tyres and are separated but still working as a team (at least, that's what Yam said)!
The tyre isse is what worries me! I think that Michelin will say to Lorenzo does what he can and what he cannot to beat Vale's 'stones because they're riding the same bikes, so if Lorenzo does better, Michelin takes the credit!
Let's see!
