Brake Line Help

[speedjohnston]

Does anyone have any recommendations on what brake line to use (stainless, steel, or copper/nickel) and why. Also a good supplier that makes everything in the same material. I am finding at Summit and Jegs its hard to get all the fittings in the same brand/material/look to do an entire system. I'm trying to get a pile of things together at the same time and searching through brake fittings is making me crazy.
