I've had the PBR Deluxe on the fronts for a couple months now. I'm VERY happy with them!
As for the dust:
I don't think that they are necessarily producing LESS dust than an OEM pad....I think that they simply produce a type of dust that:
1) Doesn't stick to the wheels as easily
2) Is a lighter colored dust that doesn't show up on wheels very well.
In either case, I'll be putting them on the back brakes when they need changing.
