I would only go with StopTechs or Goodridge lines. Both companies test each and every line at over 4000PSI before it's boxed up and shipped out. I prefer the StopTechs to the Goodridge only because they are coated so less risk of the stainless braid chewing up something it shouldn't. I'd personally stay away from the Magnum lines as they have a track record for failing after a few years. Bimmer and Audi guys had these headaches a few years ago and while the manufacturer sent out replacements, those eventually failed as well, just not as quickly.
