I would error on the side of maximum durability even at the expense of a bit more un-sprung weight. Steel also lasts longer than aluminum, and is more slippery for smoothness.
As for adding weight to the hubs, that will make the car more lazy, effectively slowing corner entry or transition. I could see it as something to try when running on a very smooth surface, but I would rather add weight to the chassis.
