The iron knuckles are tied to the KW V3's, not the RPF-1's.
The difference between the iron/z32 uprights and the RPF1/FN01RC is about the same, weight wise. I'd still do the lighter wheels with heavier uprights (as opposed the the way it is now) because while they're both unsprung weight, the wheel is also inertial and affects acceleration.
