Ball Diff's really don't like brushless power and won't stand up to the abuse very long. Add in the fact that they constantly need adjustment and maintenance and it's just not worth it unless you're racing and looking for the last tenth of a second.
I'm not quite sure about that john. I agree that ball diffs mean you have to set them properly (whereas gear diffs you just slap them in), so gears are easier. For just bashing and mild racing, I'd just say go gear diffs.
But I do think ball diffs are pretty durable with BL - or have you experienced otherwise? I've been bashing with a Durga (ball diff) and a Novak 8.5 BL setup for a while now, no issues. Same with a vintage Bosscat I was running a MM 5700 in, and a TA05-R with the same electronics - all ball diffs.
Maybe I didn't run them as often as you have? Just trying to understand where the comment comes from regarding durability.
