different brake line materials what do you use?

I've never seen the rolls of armor around. Anywhere.
And in this case useless zone wanted $64 for 25 ft but a pack of 100 ft is $104 which is 4 25 ft rolls in one package, and brings the cost per ft down to the same as what green coated line costs. I do enough such jobs, it won't go to waste. Otherwise I wouldn't have bought this expensive of line just for this truck
Starting to show its age underneath, it definitely won't live long enough to get the advantage of using the "good stuff" otherwise.
