are you serious?^^
i think that if either lorenzo or stoner were to take their teammates settings ,then the one getting anything out of it must be stoner ,keeping in mind that his team mates are closer to his size and weight
anyways,these guys know what to tell their crew , i think especially lorenzo has always done well in this area,as we could see in the ross-lorenzo years
umm if you heard in Indy, where lorenzo wasnt going anywhere in QP or FP, he said something like "i had the option of edwrads or speis setup, and went for speis' setup"
so there is free and open data sharing between the yamaha riders.
for honda different story, even gear ratios stoner has to start from square one on friday morning.
