I fully agree with the OP and also SP4X which makes also valid points. Understand the drawbacks and such, and even maybe minor differences when you perform the upgrade. But, as the OP eloquently pointed out, these guys are supposed to be the top of the top, the best ones out there. There is no place for such randomness. SP4X makes strong arguments with his tyre development. +1 to both. Hope this will be fixed at some point, or that the randomness is somewhat toned down.
