balancer coming apart

Well there's a problem. I hone my balancers as I've said here and advised before, but the bulk of everyday hot car owners don't, they just hammer them on, BUT, they don't brake a snout off from doing that. So if you look at it from that perspective, then you can see why they have been blamed for the snout failures, regardless if it's their fault or not.
As far as "balancer science" goes, well until the balancers I use start causing problems with my engines, I'm not concerned about it.
So who's they who can't be named???
