Stiff brush vs chain flail for heavy creosote - which do you swear by?

I've been going back and forth on this for months. The chain flail knocks down the thick stuff fast but I feel like I'm beating up the liner every time. Stiff brush takes longer but feels safer. What did you pick and how did it work out on a real job?

lol I tried the chain flail once and popped a hole in my liner, never again.

Cringed just reading that lol. I had a similar disaster with a cheap metal flail last summer, took a chunk out of my brand new poly liner on the second swing. Had to drain the whole pond, patch it, and then wait a week for the sealant to cure. Never again is right, I'll stick to a gentle rake and some elbow grease.
