Braided lines firm up the lever & generally give better feedback & lever feel removing the spongy feeling that OEM rubber lines give & reducing brake fade during aggressive riding

It really just doesn't matter which brand you go with or whether you choose kevlar or braided stainless steel although the braided SS lines are commonly known to hold up better in a crash situation. Nobody can honestly say they can tell the difference in brake line performance between the different brands & materials.

I personally went with Spiegler brake lines as I have found them to weather better than any other brand out there. Their anodized fittings don't fade nor corrode and all their lines are DOT approved right out of the box. Plus they can custom make a set for your bike like adding 1.5" to the length to compensate for adding Brembo Master Cylinders etc.
