Brush vs rotary whip for heavy creosote, which side are you on?

I've been in the trade about 6 years now, mostly residential work around Columbus. For the last two seasons I've been a rigid brush guy through and through, thought the rotary whips were too soft and only good for light dust. Then last month I hit a chimney with a foot of baked on glaze, the kind that flakes off in sheets if you look at it wrong. Brush just glided over it, no bite at all. Client had already paid for a sweep and I was stuck. Borrowed my buddy's rotary whip with the chain links and it tore through that stuff in like 20 minutes. But honestly, I still worry about the rotary beating up the flue tiles on older homes. I've seen one guy scar up a liner pretty bad with a heavy whip. So which do you run for the nasty stuff, and have you ever had a whip do damage you had to explain to a homeowner?

A guy at the supply house told me chain whips crack old clay tiles more than folks admit.
