Carbide or Ceramic Diff Balls

[Muggydude]

Hello from the states!

Though I would drop by here to ask some questions because you guys have had your cars for a while. A lot of us here are having problems with the diffs becoming gritty after one run even when built correctly. My car comes today, so I want to build it right the first time. It will be run in rear motor on a super high bite tight indoor clay track.

Anyways, I see a lot of you have switched to ceramic ball and that fixed the problem. In your opinion, are the ceramic balls better to use than quality carbide diff balls in this buggy (AE or BFAST)? And why?

Thanks
