Yet to see. Michelin front tyre can actually be a blessing in disguise for Rossi. He is not as aggressive in his racing style as Marquez is. Lorenzo with 2015 M1 found a sweet package in the second half of the last season. His flag to flag winning races are like a joke. Almost perfect (almost as for his initial lead he wears down his tyre a little too much hurting him in some races -Motegi?). To me he has got a perfect balanced between consistency and smoothness of Rossi and aggressive attack body language of Marquez.This is my thought.
The only thing that may hurt MM is the Michelin front tire.
If he learns how to work with that, he's going to be a frontrunner for the 2016 title.
From all the races of Marquez I have seen starting from Moto2 (not able to lay hands on his initial), he depends a lot on the front tire for aggressive leaning (more lowsides than high sides). That has to do with uncontrolled beast RCV this year was to some extent.
These changes have got me excited for next year
