A 30-year sweep told me my brush was too stiff, and my flue numbers finally went up

Last month a guy who has been sweeping for 30 years watched me work a clay tile flue in a house off Cooper Street and told me my poly brush was too stiff and I was scraping the glaze instead of the soot. I switched to a softer brush and slowed my passes down, and on my next 8 jobs the creosote came out cleaner with less dust in the room. What brush stiffness are you all running on older tile flues, or do you just change bits by chimney type?
