Braided SS vs. Hard Line

One of the biggest concerns I've read is that the braided lines allow for some expansion, creating a softer pedal and more travel before the brakes engage compared to hard lines.
That is exactly what happens. We used to try that with Dune Buggy (Volkswagon) brakes and found that you lose pedal because of the stretch.... For brakes on the road I would never use anything other than what was done from the factory for fear of the impending **** storm if you hurt someone. Just my opinion, and I am not referring to DOT approved systems like Wildwood etc.
