Stainless brake lines are a royal pain in the posterior to cut, bend, and flare, and so called "pre-bent" lines rarely if ever fit right without some serious tweaking. The copper/nickel lines with the funky green color are almost as corrosion resistant as stainless, and they're much easier to bend than plain old steel lines. fairly long radius bends can be made without danger of collapsing the tubing by hand without even using a tubing bender. Tight bends will requite a bender, but the tube is much more forgiving of slight errors than either plain steel or stainless.
