It's still to early to tell, but if you want to do some interesting reading you can search around here from last year. Jlo doesn't like it when the Bstone rears don't get the special edge treatment, Assen, Indy, Mugello, PI, Sachsenring, and maybe one or two more from 2014. It wasn't talked about too much this year, Yamaha may have found a solution or maybe Bstone were able to do the edge treatment to more tires. The only clue we have right now is that the Michelin fronts were still not good enough at the last test, but the rear is supposed to be excellent which should help Jlo. Yamaha also seem to be the fastest at adapting their bike to tire changes. MM could be the most screwed if they don't get the front fixed with the way he's always riding around on the front.
AE will do better next year with the better michelin rear, he's the only one that has been happy post testing so far.
