I prefer running steel balls with plastic hangers, delrin balls with aluminium hangers.
Altough I mostly run the mid car, I found since July the rear got some serious slop after a while using the stock part (steel).
I was going to switch to aluminum hangers but as the RB6 mid ones haven't broke yet I kept using them but switch to delrin and there is still some slop but far less then with steel, no doubt about it, even after three months of continuous use.
I run on very high grip so lots of stress on moving parts.
That car is totally awesome, and I've tried a lot.
