The 2008+ cars come with bigger calipers on the front, that may account for some of the variation you see.
It does seem that most vendors recommend a staggered approach on the cars with 2pot fronts. (12/10, 10/8, etc). I have gone that way, but unfortunately its all I've ever known. For sure putting more bias up front gives you less ability to trail brake.
I have also seen people recommending the more forward bias because they claim it helps/eliminates getting locked out of the rears, which can be an eye opening situation if you haven't experienced it (search ice mode). At some point in time I'm going to try even pads on f/r, but I bought well into the future last time sector had a sale :-)
